I have been looking for a plug-in like this for years. This a really great plug-in and does exactly what I was looking for.
I've installed it on my site: http://www.arepitas.com and so far it works flawlessly with the RSS seeds from Blogger.com.
The problem occurs with those sites that work on WordPress. Either WordPress.org or WordPress.com. It doesn't get the feeds right and does not get the last update so it shows only zeroes.
I hope you can fix this issue, if you need more details you can contact me back at [ email redacted, support is offered in the forums only ]
Also I've had translated some parts into Spanish, I can help you with that.
Thanks for this great plug-in.
