restrict basic users to basic options

Hi,

I have about 2500 users in my database. About 100 of them have a "Premium"-status and shall get complete access to the community (full functionality). The other 2400 users shall not get access to the community (deactivated in the profile type settings) but must have access to their profile data (e.g. for editing).

Now the problem is that I need to make the 2400 basic users searchable in the community. When I deactivate the users they don't show in the user lists and they cannot be searched.

How can I solve this?

1. Option 1: is there a way to make the basic profiles searchable although they don't have access to the community?
2. Option 2: can I allow access to the community for basic but then restrict the options to the very basic functions. This means that they should not be allowed to eg. see other users, do any searches, send any messages, see the activity stream etc. The only thing they would be allowed to see and do is see and edit their own profile. No other functionality.

I hope that I have described good enough what I mean and want to achieve. Otherwise please ask me for more details.

Regards,
Uwe
