scenario one: inviting someone to the community
being invited by previous regular members, is the most effective way of growth of a community. and it’d be helpful to gamify this nice feature (invitation) a little bit.
there are already some good badges for this: Promoter, Campaigner, and the Champion.
some other ways may also help this purpose:
showing the invitee avatar in the user cards: this has three benefits:
- other users can see the notwork between others,
- newbies can benefit an initial credit of old members easier,
- also the invitee is promoted each time an invited user card is clicked.
scenario two: inviting some user to a topic with the invitation button
the same way as invited users to the message are shown, it can be done for topics.
it will results to a more visible community, also people may be more engaged to help topics by effective invitations.
p.s.: sorry if the topic is not well organized. I have read it twice to be sure about the accent!
