Sorry but I'm sure this has been asked before but I couldn't find it...
Again its related to old questions that are unanswered, I've found a few questions such as
I have this problem blah blah blah, and then in comment they say never mind its fixed now, or I did this and it sorted the problem. Some of these are donkeys old and should be marked answered but due to the fact they are either in the comment, or they don't answer there own question it remains open. Whats the best course of action on these types of questions with comments.
