Regarding postponement due to COVID, our contract will include a clause about postponing to other dates if the situation gets out of control and cities and/or flights are closed.
Moscow is an interesting option if someone takes it up, and it would be very desirable to present this option before the 14th, otherwise we risk being left without Moscow and without St. Petersburg.
Moldova is probably unlikely due to the virus, borders, and flights.
In general, if 15-20 people are aware of the situation within 10 days and support the Toksovo option, I will continue working on it; otherwise, there's nothing more to be done.
Весна 2012.
