GOOGLE GROUPS i have just started a new group there for one of my other groups and i like it.
you can still post you siggys wich can include AC , your backgrounds and games etc..
you can still do challenges n all that..
its not that dissimilar to msn groups... ok it looks different but the basic concept is the same....
if you would like to check my group out just let me know and i will invite you....
then you can see how it works...
hugs claire
