I don't think any of us are disputing that the BBC are not broadcasting as much folk as we would want but if you try the BBC website you may find that it is doing a little more than you thought. I find quite useful it's archive of recordings of radio programs so that even when I miss something first time round often I can hear the bit I wanted at my own convenience.

Writing letters and emails may take time and effort but the more we do it, the more likely we are to provoke a reaction. It's unlikely that we'll see immediate results but each time they recieve something either praising a particular program or requesting something in the folk genre it helps to tip the balance when program choices are being considered. If you can take the time and make the effort to complain on this forum that the BBC isn't doing enough then perhaps you could take the time to tell the BBC themselves. I know one email or letter isn't much but if we all do it, maybe, just maybe it may make a difference.
