I'll ask around and get back to you regarding the "disconnect" issue - I'm not affected myself, so I'll have to wait for the people who are.

As for the Special:Chat links - already noticed the little "hack" and adapted it for the Vault :-) I've also made a little script which emulates the user preference behavior, but I'm sure someone with more JS experience could come up with a more elegant solution.
