Hi,
# Please create a request only if you speak the language in question and plan to write content in it, or if you are doing on behalf of specific people who do. Requests that don't indicate involvement by people who speak the language will likely be rejected or deleted.
This seems mostly fair but it's a bit limiting. One could write the language without speaking it, I suggest replacing "speak" by "know". It would be particularly important for Wikisources (where technically no knowledge of the language is needed; although in practice, it is more than helpful to know it).
Cheers, Nicolas
