Since I have so many new writer friends these days, I'm not sure who has hear of FAWG (Find a Writing Group) and Write Around the World, so I'm spreading the word a bit.
FAWG and Write Around the World
The main site has it's own blog, Write Around the World, where you'll find regular links lists to useful posts about writing and (starting later in the year) guest posts from writers, agents and editors, but this community is where you can relax, and get to know other writers from around the world.
I chose LJ because the comment format makes it easier to follow conversational threads.
All are welcome. Members can post entries but please, only make writing-related posts or comments, and no swearing - delicate flowers like myself get easily embarrassed.
It's okay to pimp your latest success, or your own blog posts (in fact, I encourage it, so long as it's writing-related), but bear in mind that, from a self-promotional point of view, you'll get more interest if you actually make an effort to engage with other members by commenting on other posts.
