Sorry for the double post. I've looked for another wiki site myself and some things pretty quickly became clear.

1. It should go without saying that a private wiki will make it necessary for everyone in the RP to sign up and get the wiki curator to add them as an authorised member. This is a bit of red tape that may get tedious when/if others want to join and don't know much of the lore.
2. People who want to join or at least get to know the RP cannot get properly informed via the wiki unless they contact us first. This will result in a barrier to entry for new players.
3. I cannot guarantee that any private wikis will allow transfer of administration rights. This may mean that one person has to be responsible for adding people. If that person is busy, access will be delayed for upwards of a couple of days. If they leave the RP, the wiki will be inaccessible to anyone new.

In light of this, I am leaning more towards a public wiki for the sake of convenience. It will mean that we will be have to be careful when handling images taken from elsewhere around the internet, but that's probably an easier trade-off than a mire of bureaucracy.

However, whatever you write in the wiki will be under a creative commons license. This is as opposed to having NO license on RPGuild. Anyone who wants to use their intellectual property for other things will have to go through and remove what they want from the wiki and here themselves.

Any comments, questions, or otherwise? I'd like to have input from others about this.
