Dear forum users, we had a recent data loss on account of my irresponsible administration.
Background information: I was experimenting with a local phpbb installation and didn't look at the URL when pressing "delete ALL the things". Turns out it was freegamedev.
Luckily our weekly backups were only 1-2 days old. Please excuse the inconvenience. I will add a stylish extension style to make the fgd forums administration look more dangerous so I don't stupidly confuse it with a local installation again.
