Prevent Password Edit

[trippy1976]

I've been searching here and on google about this. I have vBulletin hooked up to my main site. People manage their accounts there and I transfer usernames/passwords from there to vBulletin. I want to prevent people from editing their email and password on vBulletin.

It seems like it should be pretty easy using plugins to actually prevent the action (or to make it "bridge" back to the other site) or just to "hide" the options from the templates.

What's the best way to do this? Is there an existing plugin that anyone knows about?

I'd really like to know if there's a way to do this. My new class is pre-registered with strong passwords. I'd like to prevent changing per usergroup (class).
