Commenters should not be able to mark their own answers correct

It's very annoying to find posters posting replies and then automatically marking their reply the correct one. This is particularly silly because once a comment is marked "correct", the thread is labeled SOLVED. Even if the OP still has the problem. This creates an incentive for Adobe Employees to mark problems solved giving the impression that there are fewer outstanding issues AND for  experts to rack up their percent of problems SOLVED. 

So any one can post anything and then say they solved the problem, which will then bring people in using that solution. This can lead to:

1. People trying to fix problems with solutions that don't work.
2. That in turn leads to more posts on the same problem as people are going to start a new post without the alleged solution
3. Some people may be helped by the proposed solution. However this will lead to the thread being overwhelmed by responses about that solution. Unfortunately, this means the original poster's problem will be buried!

Ideally, only the original poster should be able to mark that a solution solved the problem!
