Just some questions, help pls

I am a newbie and I'd like to learn a bit more. Help pls.

1) where is the community activity? the last activity was in February 2025. Is the game dead or not? (I see that there are alliances in the worlds themselves, but there is no activity there either)

2) how can I add IFS for my airways? I configured IFC in the appropriate tab, but it was not included in the financial report.

3) will the game world ever end? I'm currently on server XIII and the year is 2041, although the server settings are prior to 1985. Will there be an end? And if there is an end, will the airline be destroyed?

4) please write some working example of a flight, otherwise it's not clear how many planes to buy and what prices to set (there was a case when they didn't give me a loan for an airplane, maybe I just didn't pay enough for the initial rate?)

5) is there a Russian-speaking community? (I'm not Jewish, if that's what you might think from my profile)

6) how do I join an alliance and will they help me there if I've only been playing for two days? I would like to join the Star Alliance, but it's closed (can I apply or something)?

Thank you in advance for any response or advice. I'm sorry if I wrote in the wrong place.
