My first contribution - sorta - to this great project
I am building a new discourse site and I have noticed a strange problem with the Bulk Invited users. When you bulk invite, the system account adds some current users to the “staff” group, also if you bulk invite with the CSV having an email, empty group field, and topic number, the invited users will be added to the staff group, with moderation permission.
I tried a few things and apparently revoking and re-granting my user “moderation” permission somehow resetted the group to the original members. However you will need to do that each time a new member accept your invitation as they keep being added to the staff group.
I have the latest discourse version built today.
