Really? I haven't noticed any that have been deleted. Perhaps they were in violation of the forum rules?
I think the main problem with posting in this (BE10d) forum is that it's now users only in here. If no-one knows the answer, and you don't have a support contract, then tough.
At least there seems to be some decent Symantec help in the 11d forum. Perhaps it's a plan to get people to upgrade ;)
