Can 2 people use the same Yahoo ID when posting on a Yahoo Group?

Question

Isn't every individual person who posts to a yahoo group required to register? Can 1 person register, then allow another person to post using the registrar's ID?

Answer 1

yes, that is possible that people share ID's. not such a good idea but it could happen, if you're logged onto someone else's ID/ account, they'd have access to all that persons group, and they could post
