The project is still in development.

SDV is currently on a business trip in China; I haven't communicated with him for a month; maybe something happened to him there...
Regarding me:
- I only played online with colleagues from work; I might not even know the basic things;
- I would be willing to come to the Moscow region; I don't know how long it would take or how much it would cost to get to the other suggested locations;
- I could pay for accommodation myself, although it would probably be cheaper if we split the cost;
- I don't have any literary data for reports.

Secondly, St. Petersburg is quite expensive in terms of accommodation; the food there is relatively cheap, but the travel...

Where did you get this information?
If, for example, we rent an apartment, how much would it cost in different regions? I have some possibility of renting an apartment.
What kind of food are you talking about? I think shawarma or instant noodles... it costs about the same everywhere.
