Yes, that's all been done but I think I found the problem. Under the 'default registration option' the box was unticked, so each member had to manuallty enable it from their CP. I've now ticked it so its enabled from the start. (its a bit tricky because many options can be found in different places in the admincp)

Although, I have another question.

Now that most of my members have this disabled without knowing it, how can I ENABLE it all for them in one go? (Without having to go through each users profile and check that box?)
