Welcome to our thread!
Let me proudly introduce a new chain-archive service!
blockchainkeeper.info
Now it works in test mode and I would like to hear your thoughts about it.
And most of all, I need a list of actual coins that you can't sync.
Now coins selected randomly, just 4 test.
Sad..
I think you have chosen the wrong section to advertise.
In my opinion, you could have a much better feedback by posting an advertisement in
"Announcements" section: https://bitcointalk.org/index.php?board=159.0
or "Service Announcements": https://bitcointalk.org/index.php?board=197.0
Good luck!
