Ten or more may be too time consuming so here is a thread for those to contemplate inviting at least five.  No need to post but it will perhaps help others to see that real people are willing to do this inviting using their own words.  Here are the words used for the five just invited:

Join our group which will alert you to ways to help the hungry including free clicking to provide cups of food for the starving. The group will also allow you to spread this message, working with others interested in hunger being radically reduced, to tell the Care2 world about the need for all to join against hunger while doing all the other Care2 projects of interest to each individually.

and the separate headlines of each invite:

Even five were too many for our real membership and only Alice's Queen of Hearts was willing to do this and the QH is a rapacious dictator in fiction.

Where are those who say they care!

[It is not a question but a sad statement of this monstrosity of indifference called Care2, which should be renamed If and only When you Care2.]
