It seems to me that a lot of people posting in this thread are concerned about "ill advice" - the majority of questions that are asked in the Community Support Forums are about the servers themselves and why one can't log-in etc. And if it does require advanced steps that an Admin needs to address well then that support request goes back to the ticket system.
There are separate boards that are specifically for questions regarding software and script usage/installation.
If I understand Corey's OP, then one can't really give "bad" advice when it comes to why someone can't log in or why the servers are slow, or how do I access my account, upload files etc, etc and none of these will ever require registry editing in any way, shape or form. Nor is suggesting that someone read the news threads about current issues going to mess up one's computer
If its server related only admins can do something about the servers, there should never be anything changed except perhaps ftp settings on the end-users machine.
When it comes to changing things on one's computer or receiving bad advice I'd be more concerned about these boards:
Site Design & Development
Perhaps I'm way off base, but I think there is a lot of unnecessary concerns, I helped a lot during the server migrations and none of the answers required anything that would give someone worry their computer would be messed up or data loss.
Just my 2 cents.
Cheers!
