Not sure if anyone's seen this before....

But thought I'd post it up anyways.

Not bad.

I found this... well here actually.

Sweet. Good work guys/girls. Those are both great sites and I will have to check them out some more. Thanks for posting them.

I haven't really spent much time looking at either site, but I noticed on the one Hayley linked that they offer you a chance to "publish" your books. Just throwing it out there, but I'd be wary of those services. Vanity presses are one thing but sometimes these things are a bit more nefarious than that.

Can't hurt to poke around though. Some of those writing prompts etcertera on there might be fun.

A bunch of good advice, not necessarily fantasy related though. (I do hesitate to call it great advice; I've run into a few things that would go contrary to what we hear from those fine gentlemen in Writing Excuses.)
There are an inordinate number of articles related to screenplays, but the major principles remain the same. Also, what I really love is that after each article, you are linked to five more related articles at the bottom!
