We have been using the Feed2Tweet plugin on our WordPress blog site at: http://www.interactivewebs.com/blog
We found that in recent weeks, it has stopped posting data when we blogged with the Windows Live Writer plugin that we normally use. So we decided to find a new plugin to take care of the auto tweeting.
We came across the “tli.tl Auto Twitter Poster” plugin. That from all accounts should work well, if only a little delayed.
The post system configures with a Twitter API registration (normal for this sort of thing), and appears to work well.
There are two versions on the plugin, one is listing as version 3.8 (we found that did not work) the other is the 3.8.1 showing as separate plugin. We found this tested fine.
