Writing Resources

I've been doing this writing lark properly for a few years now and I've learned a massive amount, enough to be helpful to others. On the fantasy fiction and writing forums I frequent I encounter the same basic questions being asked again and again from less experienced writers:

-What do you think of my idea X (very cliched idea)
-I've written something - now what?
-Er...is this punctuation correct?
-How do I make it better? How do you edit?
-How do I find publishers/markets?

With that in mind I've decided to create a writing resources page on this site that I will update with other sites and resources of interest to people developing their writing skills. I'm hoping that some of you will find it useful.
