Firstly, I want to thank you for creating and updating this simple but very powerful extension. I searched and waited for a long time for such an useful extension. I tried jix, but didn't figure out how it works. I also had a look at import/export functionality from jseblod cck. As of August 2010, it is not ready yet.
But why wait for jseblod cck when j2xml fills the import/export gap very well.
I want to mention that indeed there were problems with downloading the zip archive for versions prior to 15000005. But, fortunately, I was able to download the 15000005 and 15000006 versions. So, this shouldn't be a concern for other users, as well.
At the end, I want to make a feature request. Please add in the parameters an option to preserve the published on frontpage.
Thanks for everything. Now you can preserve the front page.
