Define your purpose
Decide what your group will be doing and what you’d like to accomplish. Use this as the basis for your Group Profile description, and in deciding which Gadgets you’ll use to help your members get the most out of the group.
Invite the right people
If you’re starting a page for a group that you already belong to, send an email to your members ahead of time, telling them why you’re starting the new group page, how the page will help your group to meet its needs, what they can expect to do here. Tell them that they’ll be receiving an invitation by email so that they’ll be looking for it.
A group that’s already active is more likely to get (and keep) the interest of newcomers. If you’re starting a new group, invite the people who are most likely to participate first – the risk-takers and innovators in your group -- so that there will already be some activity when the rest of the group arrives.
Be selective -- invite members based on what they can offer your new group.
Make your site usable
Make sure that your new members will be able to actively participate as soon as they join. Have a few Blog entries ready for them to read and comment on. Upload Photos and tweak your News Feed. Use your Text gadget to tell them about the Group’s gadgets. Encourage them to create a Profile, enter dates in the Calendar, contribute to the Blog, and upload photos.
Keep things current!
