Ten Things for the SF/Fanatics
1. Pushing a Snake Up a Hill -- SF author Jeffrey A. Carver's weblog. Also of some interest, his Advice to Aspiring Writers page (can we still call them that, or is it not allowed anymore? I got yelled at, so I've been going with unpublished.)
2. Geoff Eddy's On Creating an Earthlike Planet page, Conlanging and 3D Maps Toolkit.
3. Freelance Writing.com's Contests page -- regularly updated, lots of different contests, awards, publishing ops, etc. (good for everyone, not just the SF/Fanatics.)
4. 37 Adventure/RPG freeware programs (enter a search for the words "science fiction" and you'll get five more free programs.)
5. Ronald Green and David Lloyd's Revelation page.
6. Browse 993 dictionaries at once with OneLook.com -- try the reverse dictionary feature, it'll blow your mind.
7. David J. Parker's Resources page.
8. Preditors & Editors A-Z Resource Listings page.
9. Ralan.com's Writing Help -- home of the serial article How to Submit and Not be a Jerk.
