Looking for a simple hack!?

[yesfans]

Hope I am putting this in the right place.

I am wanting to know if there is a hack avail for 2.3.0 that would allow me to input some info in a members post from my admin panel when I look at a persons prfile from the admin panel.
What I am looking for is sorta like one you have amount of posts made or location listing in the area below the user id in posts......

Donating member: <---- this one I want to add!!!!!!!

I want to be able to have another field in that area that I can add (adding it to what appears would be to the USER PROFILE fields in my admin panel) info. I am looking to add a SIMPLE Donating Member blurb there that I can simple put yes or no there thru the admin panel and the users not be able to edit it themselves.
I know there is a DONTATION hack on this site and I have looked at it but that seems to to me to me then I need. There has to be an easier way to do it?
