I am looking for a Wiki-like webapp for an open source software community.
- Anyone can edit, no need to wait for approval by anyone. Registration is OK, but editors must be able to edit immediately afterwards.
- Viewable in all mobile web browsers.
- We don't have our own servers, so it needs to run "in the cloud"
- Built-in internationalization (an article can have French, Japanese, Spanish version, with interlinks between each language).
- Editable in most popular mobile web browsers.
- No ads.
- Either Markdown syntax or the same syntax as Mediawiki.
