Having trouble logging in since the new upgrade went live? DON'T RESET YOUR PASSWORD! Well, you can, but it isn't necessary. There's also no need to register a new account. The new version of the forum software requires that you use your forum 'display name' to log in with, rather than your old login name. Your password will not have changed. For example, I'm now using LSP_Kevin as my login name, with the same password as before.
If you're doing this, and it's still not working, send an email to firstname.lastname@example.org, and we'll get you sorted out.
