How to use

John Herbster <herb-sci1@...>

I am writing this post to find out how to use yahoogroups. I want to review messages in the TekScopes group, but cannot "get there". Yahoo keeps saying my profile (what ever that is supposed to be) is invalid and will not accept any new profile that I enter. So I cannot see anything that is posted.

Does anyone know what could be wrong or can you refer me (by e-mail) to an explanation? --JohnH
