Q is for Quick sessions

One of the biggest problems I have is finding time to write around work, meetings, family, hobbies, etc. I often find I only have half an hour to actually sit down and write, and then I think 'well I can't do anything in that time' so I end up just researching (ie, browsing the web...) or doing character profiles for characters that never find themselves in a story.

Something I need to do is to get myself in gear for writing in quick bursts. When I do word wars I know I'm perfectly capable of writing 1,000 words in half an hour, but when it's just me and the blank screen, somehow I can't motivate myself.

So I have a question today - does anyone know of a really active forum or chat room for word wars so I can get motivated and war against other people and not just against myself?
