it's absolute not the same, but it would be nice to 'meet' some people virtual. In holland we sonetimes use jitsy. I don't know with how many people that's possible for free.
I don't think it would necessarily need to be for free. Someone is probably willing to pay. Most of us would probably be happy to toss some virtual coins into a virtual hat in order to make it possible.
We all know that it's not the same as a real Convention, but it's a whole lot better than nothing at all.
It is a sad decision, but given all the concerns - and honestly any one of those would suggest that postponement is the sensible thing to do. We have all held on to the little bit of hope that things may be back to normal for us to travel, but by this time it's pretty clear that even with working vaccines, it will be a while before enough of us can get it and stop the wide spread transmission.
Many people are affected economically, so I would love the gathering to be free. But maybe as you suggested, some fundraising can be done to make this happen.
