is there a way to track User Addition and removal from groups

Question

Hi, 
 I want to track the users being added and removed from groups, is there way we can achieve this. Are there any logs to track these changes?

What exactly do you mean "added manually"? Do you mean that some users have access to /designer and are directly editing group membership from there? 
 Regarding any place in your system where group access is managed programmatically, i believe the best option as always is to log such changes into a DB table you implement that will satisfy your requirements.

Ok.. i'm not sure why that would be generally acceptable in a production system, but to confirm, there's no way to systematically track that, that I know of. IMHO all end-user-facing group management should be done through process models (etc).
