TT has been gracious enough to foot the whole bill this entire time. If, for example, four of you split it, that's $61 each. If someone, for whatever reason, couldn't swing that and had to get out, their $61 portion would then be spread across three other people. That means another $20.33. That's certainly a softer blow than asking someone to absorb $244 per month. Hell, that's a car payment to some people and you're not as likely to find as many people who take that on. Isn't the average age here something like 22? Regardless, you have a few core people that are veterans and volunteered to keep it going at any cost to them alone, so I see nothing but the strength in numbers. Instead of fearing it may go away if the admin bolts, you have the security of knowing that there are multiple people with the means and the desire to maintain it. I think it eliminates the "eggs in one basket" scenario and I was surprised to learn TT was going solo all this time anyway. Kudos to him.
I think it's great you're all willing and made the offer. I also agree that involving more people would be a challenge. People handle things at different times of the month. Some don't pay bills till the last few calendar days. You'd get random things coming in and it'd be a round the clock task just collecting money.
