I have questions on SF which I asked some time ago and never chose an answer for. This happened because eventually someone else outside of SF worked it out or I worked it out at a later date / workaround. I cannot remember what the solution was, but it wasn't any of the answers given. How should I "complete" the question so as to show it's closed? I can't close the question myself as I don't have enough rep on SF yet.
Thoughts?
Note: I understand I can answer my own question but my point is I cannot remember the answer.
