There could be any number of reasons. (1) They don't want to talk to you (I don't know why they would not want to talk to you--try sending a message asking them if you offended them in some way.) (2) They've become really busy and don't have much time to be communicating as much as they want to. (3) As Jura responded, there could be a time difference. I don't know where your contacts live, but it's possible they're just not online at the same time you are. Honestly, I live in the US, and people only talk to me when I'm online at 2 or 3 in the morning my time. =P (4) They might be shy--they don't feel comfortable writing in a foreign language, maybe. Or alternative (5) They forgot to answer you or they forgot about italki--try seeing if they've signed in recently. If they have, maybe they saw your message, but couldn't respond because they were busy at the time or there was some error on italki where they couldn't write, or something...if this is the case, send them another message, asking if they're busy or something. Or maybe they forgot they have an italki profile and they don't even sign in much anymore.

Hi Tatiana, you must always look at the time difference between countries. Also many people give up what time they can spare to answer Italki questions, but don't have extra time to communicate with you.

Well, Tatiana, darling.. These seem to be a very mute comunity for language students :( I send you a p. mesage, whit a lovely page where you can learn any language for free Keep Trying! :))

Hello Tatiana, None ?? Are you sure you are addressing ones who want to learn Russian? The mutual benefit of language exchange will motivate the others to answer you. Think of posting your real picture as well, because this silhouette might discourage many. Good luck:)
