Yeah, Thats what the entire Testing forum is for.... but experience has shown me its not sufficient.
If you'rre testing cos you have a few free hours, you post to the bboard and no one answers.. how does that help?
For the period of the testing (which is only two weeks) I just wanted to try and get a rota of experts to ensure there will be at least on on hand, direct each time.
If people can commit in advance then even if I can't cover all times, I could put up a list saying 'Expert X will be there from 10 till 14:00 on Date Y'
This would allow testers to tme thier work to when its most convenient.
