As a newbie, myself, I really like the idea of having a newbie section and a pro section. Maybe, after finally working out all the bugs in my craft, I can finally "graduate" to pro and get a little pocket money for my work. But if a newbie isn't getting any revenue in the first place, and storage space isn't an issue, why bother deleting content after an x amount of days?

I'm an amateur, a hobbyist (though maybe, with practice, that might actually change), and there will be days, even weeks where I may not be able to make any new content to upload. In fact, I'm in one of those periods, right now. If I'm afraid of having my current content deleted if I don't upload new things every so often, wouldn't that just encourage me to post "crap" uploads just to keep my real content safe? And they will be crap because I'm too busy to be able to tend to the kind of quality work I'd prefer to at least attempt to achieve (I can't say if I'm successful, only that I tried my best).
