There appears to be a glitch with the forum that seemingly prevents you logging in on your return.
We're not sure why this is happening, but can suggest a solution.
1, Log in to STT and click 'Forever' as the time period (DO NOT do this if you are on a shared computer, though)
2, participate in STT as normal, then close your browser.
3, on your return you will
appear to be logged out, and logging back in will fail, so
don't try logging in.
4, simply click on the large
Saab Tech Talk text in the top left and you will find that your previous session is restored.
Sorry for the issues, whilst we do not know what is causing the problem, we know the solution.
