Three things:
A.) Daz apparently gets tons of PMs from people, yet his PM inbox only stored 50 messages maximum–send him one while it’s full and your PM will be discarded.
B.) Even as a mod, my own PM inbox kept filling up, believe it or not. Frustrated, I eventually doubled that amount for mods through the admin PC. And as of just a few days ago, admin inboxes can store 200 PMs, so less PMs will be auto-destroyed.
C.) http://z3.invisionfree.com/MP2D/index.php?showtopic=1782
Daz be gone for a bit, PM me or another admin instead for a bit. (administrator-related stuff, of course)
So, sorry for the inconvenience.
