You can PM 5 people at a time to get your message accross to them.

Ask them for the email in a pm. Heck if they are not posting in the chapter, then they don't see your request in the thread.

Get Bud, and Joey to help. then it would be only 2 pms each to 5 members each.

Pester the heck out of them. They asked for a chapter, you put it together and now they need to support you and the chapter.

I will help if Bud and Joey don't want to help. Send me a list of the members and their usernames.
