What is the .00 (fractional NXT) next to your balance on the UI for?
Does NXT support fractional units?
- see here. Does NXT support fractional units?
I would be very appreciative if someone can send me a few coins as well so I can get started with this currency.

Thanks

- a few coins sent. Edit: Actually all these *.nxt files r wirtten and read using Java Serialization API. Is it a good approach?
It is really bad. It's better to use some java embedded sql engine like H2 or HSQLDB.I see. Now blockchain is not big, but later we should do it for sure.

Hi All.
Ive setup Nxt by following all the instructions, all seems to be working, but what do I need to do next?
Do I need to receive some coins from someone to continue? Nxt 13953498912522080539
Ok Ive answered this bit by reading..
1. Unlock ur account
2. Make sure u have at least 1 NXT
3. Make sure the very 1st transaction has at least 1440 confirmations
4. Open [Recent blocks]
5. Keep on watching the timer that says "You can generate the next block in 36 minutes 5 seconds"
6. U can close the webpage, but don't lock the account
Can someone please send me one Nxt to address 13953498912522080539 to get me started please?
Do I just leave it running to assist?
Does this earn me credits?
After about 30 minutes of running it appeared I had a balance of 2 for an unknown reason, 2 hours later I had zero, yet I had done nothing and have zero transactions all the time.
I also have over 14 digits to my password.
Any assistance welcomed. TY.

I'm not sure, they seem very corruption prone right now which is rather worry-some. They seem to get corrupted anytime I kill the program CTRL+D. Sometimes they just... explode on their own. I don't know if that's an issue with the Java Serialization class or if it's more like the data doesn't get completely flushed to the file, therefore leaving a block or some piece of data in a partially written state...
I noticed blocks.nxt is corrupted only if there is no free memory. I see "Saving blocks..." but no "...done" after it.
Can someone upload a recent blocks.nxt file please?
I have known that transactions.nxt is important too, coz blocks.nxt doesn't contain transaction info.

Give that a go, I'll try to keep this somewhat updated.
A quick question:
How can I know to which block (height) a transaction belongs?
How can I know to which block (height) a transaction belongs?
Hover the cursor over "10+". A tooltip will appear with number of confirmations. Height = Current_block_height - Number_of_confirms + 1
