If you getting deadlinks to other forum posts, Reacently the forums address changed. I think all the links in the messages themselves are fixed, but not in peoples Sigs. You will have to edit those links yourself.
Replace this in the link:
http://eqemu.sourceforge.net/forums/
With:
http://forums.eqemu.net/
And you will get to the propper place.
For those out there with links to posts in you Sig, you need to update them!
