Thank you very much, Anart and Dant! Now I understand why it's not working for me. You're right: I really don't have 50 posts yet. And probably I won't get there pretty soon, since my access to internet is limited (only at work) and, also, I wouldn't like to post anything without importance just to reach the necessary amount of messages. Oh, boy... A few days ago I ran a spellcheck of one of my messages before posting it, and, I don't know how, a correct word was replaced by a wrong one, but I didn't notice it on time. Do you think I can try to contact the moderator of the topic (via Report to Moderator option or by sending a personal message) and ask him/her to correct this word?
