Feedreader is OK but I need a help file to understand what I can, and can't do.
Can I add a new read to it from some other Blog page/service or am I stuck with just the feeds allocated by Feadreader?
How do I find which sites have the necessary file types to add to Feadreader?
How do I add a site?
What good is an application if I can't customize it the way I want?
Any help is good, TIA
