This one goes out to all the writers out there who have trouble putting out their required amount per day. I know I'm one of them.
The plan is pretty simple; we pick a partner (or a partner picks us) and it is that partner's responsibility to whip us until we get things done (metaphorically). Optionally, they may also provide criticism. I'd prefer this, but it truly depends on the writers. For the below, you may write on any subject whatsoever.
Step 1: Select your partner/be selected.
Step 2: Agree with your partner the required amount per day/two days/three days (no more!) of words to be written. [See caveats, below.]
Step 3: Agree on the time (and timezone!) by which updates are to be submitted to your writing partner to check and assess.
Step 4: Get your updates to your partner on time! If it's getting close to the time and you haven't received an update, remind your partner lightly. If it gets past the time, abuse him as much as you feel is necessary to get that update! Bear in mind this is the entire purpose of the exercise.
Step 5 (Optional): Provide criticisms of each other's work. Will not always work for everyone.
Caveats
You will need to edit five times the amount of your given wordcount in first drafts to count for an update, if you dedicate solely to editing. This is unfair - editing can take as long as writing. Tough.
If you write a whole chapter or segment and it goes slightly over or under the word count, that's fine. Don't stretch or cut just because you want to hit the count.
You can't (on a wordcount of, say, 2000/day) submit 3k one day and only write 1k the next. You have to write your wordcount at minimum (or within 10% of it). Caveat to the caveat: You can submit double or triple etc the amount if you know you aren't going to have time the day(s) after.
This all being said, I'd quite like someone to volunteer to be mine.
