can you edit your question after you post it?
If nobody has answered it, yes.
If someone has answered it and you'd like part of your question changed (maybe due to a spelling mistake or something minor) then you can contact and advsor/admin to have it changed depending on what the change is.
If no one has posted to the question, yes and if you want to edit the post you made it has to be within 2 hours of the post!!!
Only if no one has answered it yet.
^^Mhm what they said^^
