To submit a distribution, follow the rules below:
Edit this page if you have the link (See my Reddit post)
Insert a text box with the name of the language you want to submit (must be a real life endangered language, not your own conlang).
Insert another text box with your letter distribution of the language. Use the Wikipedia format.
Add notes for sounds of certain letters that people do not recognize, absent and obsolete letters (if the language is Latin-script) and if they can be played with a blank, and the creator of the letter distribution (for ones listed on Wikipedia).
