Most of the participants in this newsgroup are Russians in the U.S. soc.culture.russian.moderated was created in 1996 to avoid the off-topic articles in soc.culture.russian. It is moderated, which means that all messages are checked before they are published. The idea is good, but the flow of articles is still high. Most of the participants in this newsgroup are, just like in soc.culture.russian, Russians in the U.S. k12.lang.russian is for teachers and learners of Russian. As I understand, the k12.
Most participants are from the U.S., but there are also people from other countries.
It is not a very active group, but sometimes interesting discussions take place there. As far as I know, there is no free fax service to St. Petersburg. The best thing to do is therefore to find people with e-mail addresses in St. Petersburg and ask them to send your messages via their fax modems to the fax machine where you would like them to be received. Most phone calls are free within the city limits of St. Petersburg, so it will not cost them any money, just a little time.
