Two weeks is more than fine for judging, I'd think. It's not overly long for this.I'm leaning towards leaving the voting up for two weeks. Would you guys prefer a month? Again, allowing it too long may end up with it being forgotten too, but I don't mind throwing in a reminder every now and then if it stays reasonable.
Again, when it comes to monthly or bi-monthly, we can always adjust when we're more comfortable. Don't forget that. Same goes for the voting.
I'm working on writing up some general guidelines, and I'll be looking into having a sub-forum for the writing competitions. Thinking about creating a hall of fame where the winning entries will be displayed. Still trying to decide what would be neater, a separate thread for each story or a thread where each story has its own post. Hmmm decisions, decisions.
Edit: Perhaps we can also promote these to CMS.
