I have gotten many diremite webs from diremites. Does take a while though....Seems to be a lowish drop.

And can you not post in a certain forum area? If you are trying to post on the forums but it won't let you in general, you may have to wait a little. If you don;t play for 14 days I think, you can not post until you relog into the game. It then takes a few hours for you to be able to post on the forums again.
