hardly ever. I just have to sort through teh hundreds of pictures I get spamming my inbox from here. I think you should have narrower rules as to what is accepted, because it gets to, like, 50 deviations in the space of a few hours, and only half of them are great.
I felt the same way when I started joining clubs. I got so ticked off that I unjoined all of them untill another member contacted me and suggested I join clubs. When I cited the "spam" issue they were nice enough to point out that it was just part of the deal and everyone here is trying to get the word out about what they do. And yes, not all of the work is good, but everyone deserves a chance. I tend to deleat most of what is sent to me, I just dont have the time to look at it all. Im a pro artist and have to keep working. Hope my take on it helped out.
