first of all, i'm sad to see this thread up as i personally know how hard it was to.put up for both of you.
i say that if you guys want to close the board, that is your decision as i know that it just been you two doing all the work and that's too much to put on two people, sure you could try to bring more interest but that'll probably only last a couple months and then you're back here, where it started so why bother.
i understand where you guys are at and if you guys want to close it, you should be able to without anyone stopping you, i am on your side with this and i always will be!
