AutoTweet works for most people (see other reviews) and there is also a documentation and a forum.
Of course AutoTweet needs a little bit more customizing. But it offers a lot more functions as most other available extensions.
You have never ask anything in the forum! I do not understand people like you: This extension is free and I do thgis in my free time. You can use the extension without any payment and there is free (really fast) support in the forum and a free documentation.
It is not fair to give such a bad vote/review without asking anything! You have no respect for the work of others!
Highly recommended, too powerful for words to describe. Check it out!
It probably is better to learn by trial and error and thoughts that wake you up in the night with the answer!
