Hey, I've added a login form onto my website, and upon logging in, it's replaced with "Hey, (User). Thanks for logging in.". It then has a logout like that I would like to get working. So, any help would be fantastic please!

Get it working? What happens when you click it now?
Well, right now it's just linking to "http://forumname/forums/member.php?action=logout", as I don't know how to make the logout link find the SID or Logout key.
There's no need to keep deleting your post and reposting it, someone will reply when they can

K, well I got no reply anyway.
