when i invite some people as friends, the reply from the machine is they are on your list.  and they are not.

I'll have a look.

Apparently if you invite someone more than once, you'll get that message.  I'll add it to the list so it will say something like 'you've already invited xxx'

So you are saying we get one chance to invite someone, and he gets one chance to respond?

I ask because "friends" are automatically added to and listed as options when you invite people to join groups. 

Otherwise you must go through search for their names.  You cannot add them manually to the mailing list.

Rob,

The always-and-only list of what-points-go-with-what is under My Points in your profile.  The direct link is here.

and is always updated with any changes to the point system.

Rob, I'd think that would be by design. I'm just thinking of how facebook works for instance, you get one chance to add someone as a friend or they are "already invited".  When mailing your friends, you can't force add someone who hasn't accepted as your friend.  I'd think that would be the expected way it should work.
