All planning to go to the Marrakech meeting:

I just got the word that deadline for visas is Friday 12 February -
that is, TOMORROW.

The message is a bit confusing though:

"Our local host just informed us that they will stop taking visa upon
 arrival applications tomorrow. Applications submitted AFTER Friday,
 12 February 2016, 17:00 UTC, will NOT be reviewed."

I'm not quite sure what that means, but I presume the intent is that
visa-on-arrival needs some kind of preapproval, or maybe the deadline
is for all visas. I assume this does not apply to people from
visa-exempted countries. I'll try to clarify this ASAP.

But if you do need a visa, you're advised to apply for it tomorrow
(Friday the 12th) if you haven't done so already.
