I think contributing to the scholarship fund is a wonderful gesture.
I suspect there are many people here who would like to chip in a little something, even though they never met Rich in person. However, they feel awkward about sending a check for only $5 or $10. So, I'm concerned that if there is no way to do a joint contribution, many people will just not contribute at all.
I propose that some active person on the board use their own paypal account to accumulate a contribution that will be sent to the scholarship fund. I personally would have no trouble trusting a member of the "DIS family" to forward my contribution. However, for those who might be concerned, there are various ways to make sure that the money goes where it is intended. For example, a second active member here could be given permission to look at the paypal account and see how much was donated, and check with the family to make sure that they received the proper amount.
I am not that active here, so I don't think I'd be an appropriate person to collect the money. But, I hope a volunteer steps forward.
