No you got me totally wrong, I suppose. 
So I had an issue and supposedly fixed it. So I marked my own reply as a solution.
So far so good.
Now after X time I had the same issue again and noticed that YOU told me that my solution is only partly correct.
With the current discourse (forum) settings / restrictions I as a user have three options when this happens. (or do I miss something?)
- I write a new reply with the new solution and mark the response as solution
contra is, that the old reply is still there and could confuse future readers. - I copy the old solution, delete the old reply, create a new reply paste and edit it and mark it again as solution. (Which shifts the whole topic discussion and can lead to a discussion without context)
contra also not so nice since now there is a "Post got deleted by user" message - I ask the staff to please fix the solution with the new one.
contra I have to annoy the staff to do the edit
So whats next time when variable X changes and I need to edit the solution again?
Well... back to the three options I guess?
I did not intend to complain, not at all!
I just noticed I cant edit it and tried my best to keep the forum clean.
