There probably are ways to figure it out by probing the users machine with test cookies and such ... but I'd really rather not, and I'm sure our members would agree. :) Personally, I despise sites that want to set all kinds of cookies on my machine, that's why we don't do that on PoserPros. Just a simple login cookie is all we use. And all membership sites need cookies enabled to be able to track your login from page to page.
