The best way to donate is by adding new original content !
That can either be by contributing to an existing article, or by creating a new page with an as-yet-unlisted 'Known Unknown'.
Any registered user can create content.
Ideas for new topics, and suggested additions / corrections for old ones, are always welcome.
If you have skills or interests in a particular field, and have suggestions for Wikenigma, get in touch !
Or, if you'd like to become a regular contributor . . . request a login password. Registered users can edit the entire content of the site, and also create new pages.
( The 'Notes for contributors' section in the main menu has further information and guidelines etc.)
