I didn't avoid double post.
Sorry, but I was framed some by busy.org
Strange things happened.
It took enough time to form my first post and ...
when I try to post it - I got an alert that I'm not in account (log in).
So I have entered in account but strange thing - there are no any alerts that I have puplished my post. And no content as a draft. So I started again to form the post.
And after real visible pulishing I got the suprise of the double post.
So the first post for now is
"Shenan asks: How long did you wait for the confirmation?"
And this post I convert to second.
