How do I post the drawing questions without the drawing tag?
You should be able to create tags during closed beta, even without the reputation normally required. Just type the name of the tag you wish to use (e.g. "drawing").
As the beta progresses, the community will review and discuss how we will use tags, and what types of tags are or are not acceptable, but "drawing" seems like it is probably a good one.
You can not create tags on the mobile version of the website or within the mobile app.
If you're on a mobile device you must use something such as the "Request Desktop Version" in Chrome, or choose the "full site" option at the footer of the mobile page.
On the full site, you'll be able to create new tags.
