I've been considering putting together a business proposal, and I would like to find a place to discuss this online with other collaborators privately. I also want to make sure that the data doesn't get leaked to the public somehow. I would prefer not to have to pay much or anything, but I'm willing to pay a small amount of money if it's absolutely required. What services do you recommend?
EDIT: After having this up here for a while, I've realized I should probably add in a bit more things to help clarify what I want.
- I don't care if the host can read it, so long as they agree not to disclose it to outside sources, or to profit off of it at all. But I'm not so paranoid that the data has to be encrypted on their server.
- I'm assuming that anyone who has access to the site has access, and I don't need to protect the information that is on this site.
- I want it to be a form that promotes collaboration, a form, SE style, wiki style, anything that makes it easy to collect ideas would be ideal.
Hope these tidbits help.
