Michail,
before I joined this forum I was considering the language to use, and at the end I thought that since this is a ham radio forum, a basic knowledge of english would allow everyone to interact, the same way anyone of us would do during a QSO on the HF bands.
At the end I preferred to keep writing in english to avoid a wrong russian translation to be posted.
The last thing I would expect were the miffed reactions in the previous posts.
After all I have the automatic translation of this web site activated on my pc, so that I can read all the forum translated in english.
A little bit of ingenuity would have resolved the issue for whom who are not fluent in english, automatically translating the english to russian, saving them from venting angry comments.
By the way, there are several ham radio forums in Europe, and once in a while you'll get foreign hams registering and writing posts in english, that are replied in english, but never "welcomed" with such comments.
I was looking forward to join this forum to share knowledge and learn something new, in the best of the "ham spirit", that knows no language and nationality barriers, but it looks like it was a bad idea.
