Jane . . uk.m.f. is a Usenet newsgroup; so normally you need newsreader software to access it. However to sample it without the hassle of setting up newsreaders you can simply access it through DejaNews: http://www.dejanews.comSign up for the MyDeja option and choose uk.music.folk as a "forum" you want to view.
It's a bit of a pain using DejaNews because the system is designed to shove their advertising down your throat - but it's a good way to try it out. If you decide you like it then you can look for some News software (you probably already have some but haven't got it activated).
