Comment 4 for bug 107810

I just tested this locally, and concluded that there is no obvious way to thank someone while also marking their answer as the best. People will naturally think it important to thank whoever answered the question, and they'll use the comment form to do that, at which point "I Solved [M]y Problem" is the most accurate button available.

After forming this hypothesis I looked at the examples, and sure enough, in all except one of them the questioner is thanking a previous commenter.

So tweaking "I Solved my Problem" to decrease the number of people clicking it probably wouldn't increase the number of satisfied people clicking "This Solved [M]y Problem". It might increase the number of satisfied people clicking "I'm Providing More Information", but that's still not what we want.

I think this problem would be solved by the interface I suggested originally:
* have a "Mark as best answer" checkbox, not a button, in each comment (except for comments made by the questioner)
* make the form buttons "Problem Solved" and "I Still Need an Answer"
* make either of those buttons submit any best-answer markings, as well as submitting the comment.

As I said at the time, this would mean that sometimes the best answer wouldn't be marked as such, but it's better to have no marking than a bad marking.
