I checked out all these other group software -

Group Convert, Group Funnels, etc.

NONE of them are close to GROUPS PRO...

Groups Pro lets me automatically approve users based on a list I have in Google Sheets. This feature alone is worth thousands of dollars with the time it saves me!

It also has the same features as all the other group software above. This is one of the best kept Chrome extension secrets.

Also, the owner is super responsive and rolls out updates quickly.

Fan for life!
