When you create a group in CiviCRM there are two tick boxes for Group Type: Access Control and Mailing List. I presumed that the latter controlled whether that group was available in CiviMail, however this doesn't appear to be the case.
When you create a new mailing you can select a group whether or not this tick box has been ticked. So, I was wondering if this tick box actually does anything or if it can just be ignored?
I'm using CiviCRM 4.4.15
