OK... I have started an email group on Yahoo.
Its fairly simple to use.
You have 3 options:
-post and check messages online (on the group's website)
-post and check messages via individual emails
-post and check messages via daily digest (email with posts of the day)
You can do all 3... so its easier to post and reply IMO because you do not need to log onto the group's webpage... you can just send an email and there ya go!
Here is the email address to join the group:
IIFamilies-subscribe@yahoogroups.com
Or you can go directly to the group's webpage:
