I can chip in some money, but I can't coordinate. I'm not tech savvy, and I have always avoided responsibility for other peoples' money!

(On a few rare occasions I had to coordinate retirement parties for coworkers, but only if nobody else volunteered. As checks came in, I held them until after the party, using my own money to pay for it just in case the venue went bankrupt or something. Then after the party I would cash the checks a few at a time each week rather than having to use a big chunk of time doing them all at once. I had complaints from people saying they were having trouble balancing their statements. I would just smile and say, "I told you that it would be better if someone else planned the party.")
