The issues concerning Marrovi personally are beyond the remit of LangCom, I think.  It may, though, be within your remit to craft a policy concerning what constitutes "disruption due to insufficient language skills" (or something like that) for stewards, global sysops and local sysops to use to combat any such cases in the future.

Separately:

• If LangCom feels that seven discussion days have passed with a consensus not to close Nahuatl Wikipedia, would someone please do the honors on Meta?
• I really need one of you to have a look at the Request for Closure on be-tarask, or at least for LangCom to start discussing this. The proposer is mostly making trouble (IMHO), but the tone of the discussion is very negative, and I'd really like to shut it down.
