If you're interested in writing, you'll find a few of my favourite links below. If you're particularly involved in scriptwriting, please consider joining the UK Scriptwriting mailing list. It's an unmoderated forum for established and aspiring scriptwriters and screenwriters - anyone interested in TV drama or film, or even radio, I guess! Beginners (like me) or experts are equally welcome. Any genre, too - from sitcom to action movie, from monologue to soap opera...
The list is open to all. However, it would be nice for this to have a bit of a UK emphasis, as a counter-balance to the Net in general and the (recommended!) newsgroup, misc.writing.screenplays, in particular.
