Thanks, actually I haven't tried whether I can choose "I'm done" after upvoting the comment, but it seems reasonable.

Thanks for the tip. That also sounds well, however, I think I already have more idea than that could be written in the tag wiki.

Thanks Scott! I was looking for a more "official" way than just answer my question, but it's a good idea indeed.

Sorry if my question isn't clear. I face a lot of poor quality questions and see how others (and me) just write several comments in order to make the question clear. Also there are typcial errors people do when they ask, I'd like to find a solution, but I'm new in meta to act alone, and also don't know what would be the right way to do it.
