It appears that members are still having problems logging on to the site here. If you are one of them, try this:
1) If you have any personal messages in your regular email from a member here, open that message and then go to the link to T&TH. It may show you logged in when you link to the site.
2) If you receive the T&TH Newsletter in your regular email, open that and then go to any of the links to the forum there. It may show you being logged in when you do that.
I have not been able to log-in through the normal name/password route, but I can get on by doing either of the above. If you have not been able to log-in here, give those a try...
