Particularly great answers can be marked as a "Best Answer", so people with a similar problem can find a solution quickly and easily. The Google Help Forum also keeps track of how active a user is in the Forum. For example, you can see who is a Google Employee, top contributor, seasoned poster, or new poster.
And don't worry, we aren't removing the ability to search and read our old Google Talk Help Group content, but we have closed it from any additional posts. So, if you do have a question regarding Google Talk, go ahead and ask it!
