Enabled Group Invites

Hey Chess.com!

I have decided to enable super admins of groups to send me invites again. So, here's a call-out to all super admins of groups!

But, please consider me for admin if you would like to invite me to your group. I have joined over 150+ groups and it will be hard to contribute in your group. 

Hope to see new members and new groups :)
