Unfortunately, tutors that provide lessons for ArtTutor cannot answer questions via our Groups.
While we did look into having artists answer questions on queue, we found that other sites that promise this end up disappointing their students, because they can't force tutors to check into the site.
We do have a number of experts who will pop in and answer art-related questions on a regular basis, but they can't answer every single question or every critique request.
ArtTutor is a amazingly helpful community where members help each other all the time. So if you don't get an answer from a specific tutor, you are likely to get helpful replies from other members (many of whom are as experienced now as our tutors!).
Of course, if you have any technical or account-related queries, please send them to us here.
