I've installed a new forum management package for handling the TG discussion boards which, as you are reading this, you have already found.
The new package fixes a bunch of security problems as well us providing new functionality. The old one was produced by a company that decided they would start charging for their software and thus I wasn't able to upgrade it.
I've not uploaded/imported all the user accounts or postings from the old forums - that was going to be a hell of a lot of work.
If you really want to see something from the old board then let me know and I'll provide you with a URL that takes you there.
