I just upgraded the forum S/W to the latest version. There had been some reports of login issues, and I ran into the problem myself during the upgrade process. I found that deleting cookies via my browser seems to have fixed the login problem. Using IE6 you can delete cookies by clicking the Tools menu, Internet Options..., then click the "Delete cookies..." button from the General tab. You need to have cookies enabled in your browser for the site ( redwattleproject.com ) for the login to work properly.
