Why have so many threads disappeared and it seems like everybody has suddenly stopped posting on here?

Do you mean the old forum (not this shiny new one)?

what do you mean?
all threads should still be here some where unless the content got out of hand and has been deleted but not many have been delteted recently.
give us some hints and we'll try and help you out.

I think Ju-ju is coming in through the Findaphd.com page, and so is getting this page (http://www.findaphd.com/students/forum.asp) rather than the new one.

oops, yeah sorry guys, my mistake! I got a bit confused :$
