At T3400 I was told that I should request a sysadmin to enable Extension:Math properly for each wiki, and thus I'd like to request for it on all the three wikis I created. Thanks for your help.
P.S. Was there any guidance for it somewhere on meta? If so, please just tell me (otherwise, I'd just create a page for it in order to help other users).
