I would like to propose the approval of Piedmontese Wikisource (pms).  (Link to test)  It has been active continuously since May 2017, and has over 1,000 pages. Interface translation is complete. (There are some translations marked outdated, and we are asking the contributors on this test project to update or confirm those.) 

I will place a community notice on Meta and on Multilingual Wikisource.
