0 post usergroup

[nocturnix]

I am trying to use a custom usergroup for members with 0 posts called the "lurkers" usergroup.

It is identical to registered users usergroup.

To achieve this I created a promotion from Registered to Lurkers using post as the promotion for those with 0 posts.

In the Lurker group I created another promotion from lurkers to registered for those with 1 post.

The problem is now, everytime the user promotions task runs users are moved back and forth from lurker to registered.

I think the best way to do this would be to change the default registered group to lurkers so there is no promotion needed. instead all users start out as lurkers and when they reach 1 post, they get promoted to a custom group called "registered".

But my question is, if I do it this way, assuming both the default and custom groups are exactly the same in terms of permissions, will this affect anything else I may not be thinking of?

Thanks.
