Hi guys, I am looking for some guidance on this one.
I am building a music based social network and as part of the services supplied on the site I want to allow members to rate one another on key attributes like skills, experience, helpfulness etc.
There are a few ratings plugins that I have been trialling  that work very well, however  they allow the user to rate posts, pages and comments but not groups or users.
I am guessing that this is by design, however I want to be able to let the users make informed decisions about who to work with and which groups they find useful.
There does not seem to be a plugin that I can use out of the box so I was thinking about looking under the hood at some of the current plugins to see if they can be adapted.
Is this
A) a  dumb idea as it’s seriously non- trivial
 not to dumb an idea but will take some work
 not to dumb an idea but will take some work
C) it already exists, my search powers are deeply woefull
D) not possible,you need a custom plugin to achieve it
E) sign of a serious lack of socialisation
If you could point me in the right direction I would be really grateful.
