Oh.
Rich,
You had me confused, but on re-reading the message I understand what you're saying. At any rate, I try to reserve "postes flambe'" for special occasions.
Anyway, these days MOST forums have a simple sign-up page, but not everyone does. No matter what the situation, I think that setting up one or more free Yahoo!* account(s) can make your life easier, and you can decide at any point to stop checking that account and wash your hair** of the whole thing. After all, giving out a throw-away Yahoo!* address isn't quite like giving out your SSN any more.
Yahoo! even offers 'disposable' addresses now. I have no idea how these differ from the addresses they've always offered (which, after all, were pretty much free and disposable), but it's a great marketing concept.

* Or whoever -- there are a lot of free email services out there.
** Or whatever you like washing most.
