As offroadgeek has pointed out, the database is lost and is irrecoverable. I say lets not dwindle on this and try to put back the data that was there as best we can from memory.
I suggest that for all posts made in the past 4 days that people can remember they put back into the original post and put in the letters "REC" in the subject line to indicate it's a recall of the post that was once there.
For example in the X11 ROM forum there was a post about MPLAYER. I will recreate this post with the subject: REC - MPLAYER and try to fill in as much as I can remember from the posts in that thread.
Are you with me?
