Hi all,

Im having a problem adding multiple users to a ChatGroup. I want to add multiple users to a ChatGroup but i cannot figure out how, can anyone suggest a solution or point me to somewhere there is one?? I can create a user group and add the user that created the user group but i cannot figure out how i add other users to the user group, any ideas??

Thanks very much for you time…
