Basically practically all pages inside Momo wiki are editable by all Momo group members. To edit, create a link in a document first and then click on that link. You will then be asked to create a page.
To edit an exising page, click on the "Edit (text)" link that comes up when you move your mouse over a pencil icon above.
While you are looking at the top portion of this wiki page, please note that there is a navigation menu startig with "Home" and ending with "Help". You can put any personal links in between these two links, by using "Settings → Preferences".
Feel free to create/edit/rename/delete any pages. The backup system is reasonably extensive, and so even if you make a mistake, it will probably not a big deal.
