ur a mod denis, u lot dont get the same rules
This forum software seems buggy at best on most days, but back on topic:
I've never had that problem before I was a mod, and I used to PM allot every day. Possibly some spam filter in place due to all the excessive spamming the forums would get otherwise.
So if someone has an important question that they don't mind sharing with the community just post it as a topic title.
