Just wondering...

[James McIntosh]

If a user signed up for an account on my web site, would James_McIntosh be the same as James McIntosh, just in like ways of if I sent a PM to James McIntosh thinking it'll goto James_McIntosh for an example?

if you want a hack that will verify these situations, once you are a licensed owner you can request this at http://vbulletin.org ... this is a simple 3 lines hack that would take 2 minutes to write.
