before i had to upgrade to 1.6, I was using a free version of another Auto Tweet Application, it worked most of the time, then when i upgraded Joomla, I almost had a panic atttack looking for something to replace the one I had. This did the trick. setting it up was pretty easy to set up. though I did most of the goof ups on setting it up because I did, before I read. there is great support for this, and is worth the price for this.
If you have to post then tweet this will save you tons of time. Great job!!
