Users end up joining independently when they verify their email address even if they accepted an invite

[klaith]

Because the Invitation status is defined as a char in model but referrred to as int in code the expression:

if join_invitation.status not in [5, 7](line 183 in models.py)

always evaluates to true if you are running postgresql as chars are not integers.

I suggest changing the status field to an integer.

sorry - just seen its been fixed in the latest release
