Given that part of this scheme is to run some donations to PL too, and that some measure of completeness might be in order (otherwise how do we know enough is enough?) could Spec help? Some page with a script on it, that keeps count and issues a PayPal invoice sending direct to Winni? And to PL? Two separate payments, that way no single payment gets done twice, and we can all see how much got raised. As an unusual extra raise for PL, this might be in Spec's interest to code for it. He seems to know code very well for things like this, better than the host of any other forum I've posted on. This way we'll have a mechanism that can be used again if ever needed. (But the idea is that if we all own a right to something more than passing opinion, it gets less likely that anyone will risk that much damage to reputation and chance at work in lasers, so we might never need it again. But making it a permanent possibility can be good deterrent.)
Edit: I know that Spec has a donation thing anyway, but that's not the same. People with no PayPal account can't use it anyway, and some may prefer a one-off donation. PayPal invoice works best for that, because it can direct to one single routed payment, and does not require a PayPal account for the sender, only some card that will work.
