once we code the majority of all the features I might make a upgrade script. The advanced use system allows features to be turned on and off, profile field tags add easily from the admin cp, new user groups added easily also. We are currently working on both of those. As well as many other things.

Hello Admin,

the profile field tags is something i'm working on already its just at the bottom of my list right now as for turning features on/off its not something that really applies to me yet as i dont think id really be using that in my personal system but as a public release that is a great idea, if i can help with anything let me know.

Well in our advanced version we have and will have lots of things that a user might or might not want. Feartec is working on the user profile script, so Im sure he would like it if you worked together. :)
