Umm I don't know who that someone else is, point me to the thread and I'll go see
I never knew the email address would be in different variables ... to me it makes no sense.
What really baffles me is how the host can insist on something like this that doesn't appear to be easily accomplished on one of the biggest forum softwares out there. I mean I know (ok assume since I can't "know") that 98% of all vBulletin users don't have this retarded one click opt out. I haven't found a mod anywhere that does this.
But, I have seen other places that automatically opt you out by clicking a link sent in an email, but I have no real idea how. I assumed it was a javascript and all it did was delete the address from a mailing list. Either that or it was a completely bogus opt out

Which to be honest is what I'm thinking of doing until I get a real working solution
It wouldn't be hard to pull off (I know hostmonster will check I've raised too much hell over this for them not to once I tell them it's done), just disallow registered users to subscribe to anything, then run a couple queries to deselect some options and viola! the wool has been pulled over their eyes
