Well, You have invested a crap load of time, effort and $$$, into the board to keep it up and running. I would say keep it up and running if for no other reason than the investment you have already made in it.
That being said, perhaps you feel tied to the board now, Maybe your no longer getting anything out of it and it's just a Pain. If that's the case I'd say sell the board, the servers, the domain etc, to someone who is interested in doing it. Literally wash your hands of the whole deal and find someone who is excited about the whole prospect. Hell I'd buy it if I knew where I was going to be living, and if I knew there would be a place to house everything.
You won't "charge" for the site, you won't ask for donations, yet this comes up every six months or so. Doesn't make sense, I'd say take the failed "Buy The Captain a Busa" money and use it for board expenses. Then Create a couple of banners on the board for the T-shirts, Hats, etc.. So those keep moving out the door And lets move forward.
How about a break down of expenses? The Real down and dirty monthly costs of hosting and housing the board. Specifically What's the Bandwidth Usage per month? And how much storage/HD space do you use? There are all sorts of hosting possibilities out there, and I wouldn't hesitate to ask folks for $5 a month or so to pay the expenses. Would provide a reliable trouble free method of keeping the board up and running without stressing out your members every six months with threats of having to close up shop.
This board is unique in that there is a lack of porn, a lack of racism, a lack of shiddy Teenage attitudes (well... besides me I mean), heck a lack of harsh language. It's NOT a mechanics board, it's not where to go if your looking to start some shid. But it's the place to go when your new to the Busa, New to web boards, still got your Green "Newbie Shell" on and just need some help, or place to hang out, to find some other folks to ride with, to really be part of a little virtual community. That is what makes this board unique and different. There is a real sense of civility here, and for the most part a lack of attitude and BS. (again besides me and my attitude of course) It's the fact that right now, I could plot a trip from coast to coast in either direction N-S or E-W and have at least one or two members in every state on the way I could call on if I needed a hand, or just wanted to stop and BS for awhile...That's What makes this board special... IMHO.
Otherwise, yeah there are other boards, Other Hayabusa boards, Local boards, etc. Where folks could get questions answered, get some advice and tips, and information on get togethers etc...
