Thanks for your answers. @Peter: Exactly. I've found something similar on http://help.tweetmeme.com/2009/04/06/tweetmeme-button/ But I don't want to use a foreign service for that. The Tweetmeme-Retweet-Button would have been perfect, if it came directly from Twitter.
The functions of Tweetmeme that are interesting for me are: - integrated shortener service - counter for tweets - tweet by one-click-solution Functions of Tweetmeme that I do not like: - third party solution - tweet string := title of page and not editable - tweet url ist not editable Maybe there is a solution out there?
