I installed the group plugin, and then added another member to a public group. I even bumped the member to a moderator.
That part worked perfectly, but there is one small issue.
On the groups activity page, it says user 'x' joined the group. The 'x' is the proper name, however just to the left of the username is my avatar, and not his.
first activity says 'steve' joined, yet the avatar is my avatar, not his, and the avatar also links to my account not his. That will make it a bit confusing to users?
