30 invites/day
A group's admin is allowed to invite 30 members per day. Chess.com has grown so big with hundreds of thousands of members. I think the invite per day should be 50 instead of 30. What do you guys think?
To contact members of your own group, you have all of the other mechanisms available (e.g. group forums, notes). To people outside the group, receiving an unsolicited invitation from a stranger will generally seem like spam. Increasing the number of admins within the group will enable the group to send out more, in any case.
