Is there a way you can add more than one people to your group at a time?

Nope, you can add only one at a time. It would however be a nice addition for the capability to add more then one user to your group at once.

Don't argue with idiots because they will drag you down to their level and then beat you with experience.

Other than being silly and opening multiple instances of your group page in a PC browser, no. Groups are expected to be updated, however I wouldn't be one to advocate actions like multiple user adding. Most importantly it's because mass adding leads to just that--spam adding members, which though efficient for owners, may be annoying for invitees and irking for owners who would now have unfair advantages in the healthy competition for Popular Groups. I also feel Groups should be significantly updated, yet not overly convoluted in order to increase their popularity and ease of use just a smidgen.

Catch my drift.

I wish, that would be a fast and easy update. It could be called "User Tags".

Doesn't seem like you can.

Seeing as the answer is out of the bag and nothing new is being discussed, we can all temporarily direct talk of website suggestions to the much-used suggestions thread.

Catch my drift.
