The forum is back. Sorry for the long time it took but it was way more difficult than expected. Sorry also that over 4 months of messages have been lost.
As I said on MRC, I'll try to make more frequent backups from now on.
Nevertheless having said that, I am still puzzled to understand why and how the SQL database vanished suddenly and hope this won't happen again.

Same here. Thank you very much for your hard work, as I know you are quite busy nowadays. Again, thnx!, we are back! 

Switch to PosgreSQL!

Thanks for your efforts, you've done a great work here!
