getting back to the point of this post which I think it is giving support to the users, now I am thinking it better and a pre-configured group is actually a bad idea, have a lot of problems, first some mechanisms to add the user to the group are needed, the group size limit, the user may get too much ‘spam’, the user address will be shared with everyone in the group, and maybe the user don’t even talk English in the end, etc
IMO a better way to get support could be using a preconfigured bot like DeltaBot: an email bot assistant which could provide help to guide users to the channels where he/she can get support (ex. sharing links to de IRC channel, etc) and could answer FAQ, etc.
PS: @STPKITT users can’t leave group because to leave a group you must send an email to the group saying you are leaving the group but since you can’t send an email to so much people, the message is never delivered and your email server send you an error email saying so.
