Creating a 'BETA' network.....


I would like to offer a 'beta' of my MU install to users that I already know.

My main objective is to make it secure so that blogs/posts will not be lost and when I go live they have a separate account level.

This way I can offer them advertising free blogs 'for life' - i.e. when we go live they will have a different level that allows them to have premium access as a reward.

Its a simple concept but even with your plug ins I am getting confused about implementing it.

Has anyone else done this - if so, how did you implement it?

Or can anyone clear my head of the clutter and simplify it for me again?
