This has recently had an update, and i must say its tons better.
clean-up process has been improved, and although its early days im no longer getting disk space used up at an alarming rate on my server. XMl has been rewritten too apparently. and there is a nice right click function to save time when building post templates.
It takes time to experiment with feeds from all the networks, EG- pipe, comma, gzip, zip, XML, CSV, Many still throw errors up or fail to fetch when using this plugin, its a case of trying all the feed options until it works, and now it mostly does work.
