sigh.. solomining 550kh solo to get my first block and join the pool, first day no luck (1 stale 
)
Hope theres something in the works to make the pooled mining easier. I like the idea of the coin but it cant be a success if its near impossible to mine solo and to pool mine you need to solo mine first.

You mean get Gridcoin on an exchange?
we should really consider going for exchange market now. otherwise we will die slowly.

I occasionally get that. Just delete the blocks and chainstate folder as well as your peers file in \AppData\Roaming\Gridcoin and let it redownload the blockchain. Takes about 5 minutes but it'll be caught up again after that.
Did that but it seems i lost an unconfirmed block that I had mined :-(
If you lost it, it means that it hadn't been taken into the chain. Since you got left behind, you may have found that while you were lagging so when you caught back up to the chain, it deleted that block since it wasn't finding it now that you caught up.
Actually I was synchronized with the blocks when it was unconfirmed and then I restarted the system .. upon restarting there were problems (and then later repairing by deleting blocks,chainstate and peers it worked) ... it was no longer there when I resynchronized.
What happens is that at some points the client will get stuck at a block (even though it says that it is correctly synced with the network), since the client thinks it is synced and is not receiving any new blocks your miner continues to mine on the block that it's stuck at until either it solves the block or you restart the client.
If it solves the block your client will say that it is accepted because as far as it is concerned this was the latest block on the network, but when you restart and re-sync properly the transaction will disappear because it was never valid in the first place and was never even a part of the original blockchain to begin with.
The easiest thing that I have found to do is to check in on my miner occasionally and compare the times between the last time a block was detected on the network and the current time - If only a few minutes have passed then everything is probably fine, if it's been 30 minutes or more since the last block, odds are pretty good my client has stalled and needs a re-start (usually with the "-rescan" option).

Ok my client seems to be stuck on block 30603 while synchronizing ... what do I do now ? (I already tried adding the nodes and also tried upgrade command (which fails) along with restarting the client ....... none seem to work)
In a command prompt type the following:
Code:
1) cd c:\Program Files (x86)\Gridcoin
2) gridcoin-qt -rescan
2) gridcoin-qt -rescan
If that does not work, do the following:
Code:
1) Open file explorer
2) In navbar type: "%appdata%" (no quotes)
3) Open "Gridcoin" folder
4) Delete everything except "wallet.dat" and "gridcoin.conf"
5) re-launch Gridcoin
2) In navbar type: "%appdata%" (no quotes)
3) Open "Gridcoin" folder
4) Delete everything except "wallet.dat" and "gridcoin.conf"
5) re-launch Gridcoin
Thanks will try it next time

You can still setup a traditional pool, it will be without the Boinc subsidy however.
I'm not so sure about that.
I mentioned this earlier in the thread that when I was mining on my laptop, if I had BOINC running and an instance of pooler's cpuminer working through the loopback address, I was able to use my my gpu+cgminer from my desktop pc and was still earning BOINC subsidies when the gpu miner found a block.
I stopped though because I knew this was not how Gridcoin was intended to work.

Yeah, I'm sure it would have to be a lot more sophisticated than a typical pool. Hopefully he will chime in with his predictions on the future pools..
Alien, I know about that 
I mean when the coin takes off even more and we see the trend towards independent pools turning up.
Yes, there is a native pool available by setting poolmining=true in the gridcoin.conf (I have not used it myself)

Will pools need to be specialized for Gridcoin/BOINC?
I think I'm going to do some research into pool operation
I think if the cpu mining thing works good, that would be great. You can still mine in a traditional pool just without the Boinc subsidy.I think I'm going to do some research into pool operation

What kind of graphics card do you have?
Is there an easy way to purchase Gridcoin at the moment? A thread for buying / selling perhaps?
I also have BOINC open on one of my computers from the XRP giveaway, how many Gridcoin can be mined per day on an average machine?
Love the concept - would like to get involved soon

Does anyone here need any paypal? i need btc or ltc.

It was most likely an orphan which happens occasionally when solo-ming. This is when someone solves the block on the network just before you do. Your wallet shows you mined the block but once it is check with the network it is invalidated and shows up as a "?" and usually disappears once you restart you wallet or reindex to the blockchain. Have you tried the internal pool yet? (setting poolmining=true in your config)
No I have not. Is the payout proportional to the hashrate or something ? And any more settings besides poolmining=true to be set ?
I was under the impression its only solo mining.

Thanks for that .. will wait and watch
