Several WikiProjects have been created, here is the top level list that branches down to individual projects:

Jeźli na powyższym wykŏzie niy widzisz WikiProjektu, kery ôbyjmuje Twoje baczyniŏ abo przestrzyństwo w jakim chcesz sie sam ryalizować, bez chwiyraniŏ zaregistruj nowy WikiProjekt!
For categorizing WikiProjects, use appropriate subcategories in the form of Category:Geographical WikiProjects (for WikiProject France, WikiProject Rivers, and so on) and Category:Sports WikiProjects (for WikiProject Baseball, WikiProject Basketball, and so on) — not Category:WikiProjects Geography and Category:WikiProjects Sports.
If you wish to suggest a new WikiProject (instead of creating one yourself), don't hesitate to put it on the talk page.
Joining a WikiProject
Everyone with an account can join an existing WikiProject. Each WikiProject can have a list of participants in a subpage "Participants", which allows to use {{Ping project}} to ping all the listed participants. The names of the users who have been inactive for more than three years (or for more than one year, if the list exceeds 45 names) can be moved to a subpage "Participants/Inactive", linked at the top of the page; when moving usernames to the "Inactive" subpage, please ping them in the edit summary or send them a message in their user talk page.
Data about WikiProjects across Wikimedia projects
Wikidata also has structured data about WikiProjects in other Wikimedia projects such as English Wikipedia. You can explore this data for example at Wikidata:List of WikiProjects.
