Issue with unity answers

I got my question deleted in unity answers and the following message:
This question has been rejected by the Unity Answers Moderators. If you believe this to be in error, please contact Unity support."

Well, I believe to be an error, but I don’t know exactly where is this Unity support. The “contact us” in the website doesn’t seem suitable. I’m supposing it can be here. Anyway, this was my question:

Title: How to 9-slice but not in UI?
Description: I know that buttons and possibly other UI elements in unity have pretty straight forward 9-slice scripts for images. But I would like to apply 9-slice outside an UI canvas. I’d like to have a 9-sliced sprite in an arbitrary position in my scene, so I could make a text balloon that would appear above NPCs heads for instance. Is this possible by default in unity? If not, anything free in assets store? any good method to do myself?”

I have read the FAQ in unity answers and I don’t see why this question would be inappropriate.

You can use The 4.6 GUI and set a Canvas to World Space. Then you can put the text balloon inside the world space GUI and put that over the head of your NPC.
If you do not like to use the GUI at all you have to create the Meshes for displaying a 9 slice sprite yourself.

Oh, nice, thanks, I’ll try the canvas thing out and see if it goes well.

Your answers post was rejected because it’s a general question more suited to the forum.

Oh, ok then. I had another question removed for that reason too, I’ll remember that next time. But It would be better if you could put the reason already in deleted questions, so I wouldn’t need to go after what happened. My first question removed had the reason showing below the question already, that was nice.
