So we can no longer ask questions here or see anything on Tumblr?

Not quite.

We will still post challenge prompts here and the challenge runner may also post the art here as well… but it won’t be our primary gallery and they aren’t obligated to.

And questions should be left as comments/messages on the DA group or sent to http://30minchallenge.deviantart.com/ for promtest response as this is no longer our primary page.
