Another Suggestion:
Switch from the current "Site Admin owns all works" style of TOU to the more flexible, user-oriented Creative Commons License.
With a Creative Commons license,
you keep your copyright but allow people to copy and distribute your work provided they give you credit -- and only on the conditions you specify here.
The one which works best for a site like storycrafter (in my opinion) is this one:
Attribution Non-commercial Share Alike (by-nc-sa)

Choose by-nc-sa licenseThis license lets others remix, tweak, and build upon your work non-commercially, as long as they credit you and license their new creations under the identical terms. Others can download and redistribute your work just like the by-nc-nd license, but they can also translate, make remixes, and produce new stories based on your work. All new work based on yours will carry the same license, so any derivatives will also be non-commercial in nature.
-------------------------
So what exactly does this mean?
The originating author (i.e., the storycrafter) retains the copyright for his/her original concept, can alter it as he/she sees fit, and can use it for commercial gain. Others are welcome as well to use/alter/create derivatives (in the case of storycrafter, this allows for contributors to participate in a story) -- and they retain copyright over their individual contributions, provided they attribute the origin of the piece to the original author (the storycrafter). They cannot take a story and claim it solely as their own, nor can they profit from it. The originating author also cannot take the newly created piece (what develops via shared writing) and profit from it solely -- he/she can ONLY profit commercially from the original concept, before any outside contributions/alterations.
This prevents a person from putting together a group of writers, then taking the whole finished work and attempting to sell it for personal gain. Not that that's likely to happen -- I've only heard of one story every going commercial, and that was on the originating website (
http://www.cityofif.com)
It also prohibits anyone who is either participating in the story or just passing by it from taking it and selling it.
The biggest reason for this change would be to allow the storycrafter to retain copyright over HIS/HER work, and all contributing writers/players to retain copyright over THEIR works.
I understand WHY the TOU is as it is -- to protect storycrafter.com from lawsuits -- but the creative commons license would circumvent that and protect everyone using the website.
