This addon aims to add some functionality that goes missing if you use VinceRaidFrames and disalbe the default group addon. This addon lets you accept join request, invite requests and normal invites. That is all it does. I hope it can be useful to someone out there. This addon is based on InvAccept. I just added some more functionality.
/convertgroup lets you convert the group to a raid if you are the raidleader.
