Two different approaches to remove feeds you subscribed
IM (Skype, MSN, Gtalk)
In chat window with Anothr, you can input "- [feed id]" that will be ok, e.g. if you like a BBC news from your subscription, for example, ID of BBC news in your subscription is 3, so you can input ' -3' (can't input quotation marks).
On the web, visit
http://www.inezha.com/user/reader and click the right button of one feed you want to remove, you can find "delete", and click "delete", then you can remove the feed.
Welcome. If any issues, please let us know.
Have nice weekend!
