Can we stop you guys marking your own answers correct?

Yes you can if you are a mod.

But I agree the correct answer does not work here on this forum anymore.

All too confusing: nested replies, different quenstions in the same thread. Its a mess.

You can not mark your own answers as correct.  It does not work that way.  Thank goodness. 

When someone replies to you.  Write them a response letting them know if their answer solved it or not.  This will let moderators know if the person actually was able to answer your question correctly.  If you wait two weeks to reply then someone might assume that your question was answered.

Harry,

I have learned two things that may hopefully help you and others manage the marking of your threads:

It is necessary to be signed in to see the clickable Correct Answer option at the bottom of the post in question; it is possible to go to the forum, maybe following a link in an email notification, and see the post without being signed in. You can see whether you are by the avatar at the top right of the web page, or click the Sign in button there if you are not.

When you can see the Correct Answer option in the post, you can click it to mark an unmarked post as (one of) the Correct answer(s, there may be multiple Correct answers), and equally importantly you can also click it to unmark if the post is wrongly marked as a Correct answer, thereby setting things right.

Harry,

I have alerted some (other) friends about this issue for further considerations.

I have to say I've been finding the "Correct Answer" frustrating in the new forums. Quite often, someone, not the OP, marks a post as correct that quite obviously isn't a correct answer - it almost feels like they used "correct" as "like"?

I don't know. I just feel like the "correct" answer has been less correct since the move to the new forums.

I also don't think the "correct" answer should be highlighted or displayed on the community discussion page. Because there can be more than one "correct" answer now, and listing only one is extremely misleading as it's only the most recent to be marked correct. More useful with this new method would be to have a field: "Number of correct answers: 5" or something like that. In my opinion.

You do have the ability as the Original Poster to mark a reply to your thread as correct.  I would also expect that since you are able to mark a post correct, that you could mark a post not correct.

This user, not a moderator, was able to do so:
