Yes, validation is publihing.
Now, I review my links and pages, and the diplaying bug is no more. I don't understand. As if a timer would work !?

Editing the page and reloading after, the issue has disappeared. Now the page works well. How I can do to know which other pages are using such Latex formulas?

Is a particular module missing, or do we need to activate certain gadgets?

Hi!
A precision that can be useful. In Kotava, the standard for most punctuation marks, as ( ) ~ ; « » ! ? – —, they must be separated from the text, by unbreakable spaces. For this reason, it has become customary to insert them in articles in the form of (   ) ~   ; «   »  !  ? etc. Unless a better solution* could be found, they should be kept by not converting to simple spaces.

Hi!
Etc/GMT is the code for Greenwich international hour.
Since Kotava is an international auxiliary language, we think this default affectation is logical.

I'm test-administrator of this project in the Incubator. If some precisions are needed, I can give them, I think. Cheers.
