We are having these issues on two of our forums, so I don't alway sremember what I said on one and not the other. Let me summarize some a few things:

There are a few issues we have not fixed. We've pulled in the vBulletin people to help as we believe the software is causing the issues. This is specifically true of the speed.

So - we are still working on the speed.

Membership list was disabled by us. It was one of the things we looked at to see about increasing the spped. We'll see if we can get it back after we get the overall speed issues resolved.

Search should be working. I'll test it as soon as I'm done with this post.

Finally - Alexa #s have always been off for our sites.
Brad!
