Does anyone know?

As super admin for a group am I the only one that can invite new members or can the admin or any member invite others?  I ask because I see new members that I've never heard of before.  thanks !

Your admin can invite people/accept requests too.

Note to future posters: No, it is not a public group. I checked. 

So the regular members can't invite., correct?  what does a public group have to do about? thanks

If it was a public group, anyone could just click 'Join' and they'd be in the group. Yours, however, I have to send a request to get in.

So just expel all your lower admins if you're really uncomfortable with new members which you havn't invited yet. joking.

thanks guys. The new members aren't a problem just wondered about the rules.

As I'm "2nd Admin" so to speak, can I approve new members etc.? - I think ONLY the "Super Admin" should do that, nobody else..- Alf

Well, Aminor, you COULD, but you always have the option to just let scut_fargus do it !

Don't know if you can, being just an Admin, but go to group homepage>manage members. This should give you a list with delete/ban options for members.  I wouldn't rush into it though and create a bunch of hard feelings.
