I was wondering what happened to you! I always thought you were a cool dude and your photos were some of the best. Regardless of if you decide to collect again or not, it's always good to stay in touch.
I think selling your stuff to maintain a business/dream is admirable, and a very rational thing to do. If you want back in the game though, I say go for it! You can always just sell your stuff again to someone who's willing to pay too much for it.
Glad to have you back.
