[Script Frenzy](http://www.scriptfrenzy.org/) is starting April 1st. I don’t know enough about it to endorse it, but some readers might find the faux-competitive nature of it motivational.
> Script Frenzy is an international writing event in which participants attempt the daring feat of writing 100 pages of scripted material in the month of April. As part of a donation-funded nonprofit, Script Frenzy charges no fee to participate; there are also no valuable prizes awarded or “best” scripts singled out. Every writer who completes the goal of 100 pages is victorious and awe-inspiring and will receive a handsome Script Frenzy Winner’s Certificate and web icon proclaiming this fact.
It sounds like [NaNoWriMo](http://www.nanowrimo.org/) for screenplays. One hundred pages in a month is an ambitious but achievable goal.
If any readers end up entering and finishing, please [write in](mailto:ask@johnaugust.com) and let us know how it went.
