PortlandWiki is a wiki, which in its simplest terms is a collaboratively editable website. For PortlandWiki, this means that, for the most part, anyone can edit anything on PortlandWiki. Anyone can correct a typo, anyone can improve wording, anyone can update out-of-date information, and anyone can relocate or change what they feel does not belong.
To assist in this open, collaboratively editable environment, it becomes necessary that all content added to the wiki (with some exceptions) is freely licensed, so that others may easily copy, modify, and improve. Therefore, whenever you make an edit, you automatically agree to release that edit under the Creative Commons Attribution-ShareAlike 3.0 Unported (CC BY-SA 3.0) license. In a few words, this license allows anyone to copy, modify, and adapt your content, as long as they give you credit (in PortlandWiki, you are automatically given credit via the page's "History" page) and release their own modifications and adaptations under a similar license.
Occasionally, you may see some text inside a box that looks like this: Template:Copyrighted text
This is an exception to the rule. Occasionally a copyright holder (for example a professional writer, company, or institution) is generous enough to allow their content reproduced in PortlandWiki (where it is available for all to see, for free), but doesn't want it to be altered. These wishes are respected, and such content is exempt from the default CC BY-SA 3.0 license. If you see this box on a page, do not edit its contents except to correct any mistakes in the transcription. If you see that someone else didn't understand and edited the contents, please change it back if you can, and explain why to the well-meaning editor. If you would like to use this box, see Template:Copyrighted content.
