I just got back on the UT today after a few days out of the office. I had the UT on and minimized at work (just forgot to reboot and only locked the machine). I have just been reading messages posted since Thursday and I didn't see anything that was rude in any of your messages. Then of course I had to reboot my machine for another reason and had to use the time warp feature to read old messages. I never know when I do that if I'm actually seeing all the messages I've missed or not. Sometimes I would really like the feature of only browsing those messages that I have NOT viewed during the past week. I understand that Michel cannot realistically track that though. I would not concern myself with it Naomi. Has this person responded to any messages on the UT recently? If someone is not responding to your messages right now there could be any number of reasons:

Too busy
Not at their desk
Accidently twitted you
UT on and minimized but doesn't have time to read messages or is not there (typically what happens with me - I almost always open the UT up but minimize it and read messages when I get the chance).
Doesn't receive emails for all responses (I turned that off myself).

If it is really concerning you and you haven't heard anything back in a couple of weeks (they may be on vacation after all) then ask someone else privately to ask the other person if they twitted you or not.

>>>Easy. If you try to send a Private message to a person, who put you in your twit filter, you would get a rejection.

>>I didn't realize that, as I rarely use it, but it seems proper. If someone doesn't want to read your public messages, I doubt they want your private ones either.

>>>Now I was trying to figure out, what action of mine prompted it. In any case, I'm really sorry for that, but unfortunately this person would not see this message.
>>>
>>>I'm thinking of writing an apology e-mail, though at this moment I don't really know for that.
>>
>>You are worrying yourself needlessly. You can't please everyone all the time. Let it go.
>>
>>And I agree with you on Peter's suggestion to make the Twit filter public - no way. It's a private thing, and no one's else's business. Whatever the reasons.

>The problem is that I considered this person as a friend and I really wish to at least understand, what wrong did I do this time. It does upset me a big time...
