You can move your existing post (by editing the title--same place). While you're reading, check out the Community Guidelines and the note about not cross-posting:
I also wouldn't worry too much about what category you post in. Unlike traditional forum software, Discourse (what this runs on) makes it easy to see posts in any category, and most staff and and many users look all over, but I'd still make an effort to put it where it fits best. Coding questions only really seem appropriate for the "Developers" category, where yours was already moved by the time you replied.
