Thread:Support/Changing the MW source/reply (2)

Thanks for showing the interest. :) Since I have no previous experience in co-working with the dev team, I might ask rather fuzzy questions till we come up to a solution. Concerning this file:

languages/classes/LanguageSr.php

Might it be permitted to call $wgUser on purpose of distinguishing registered and not registered users within the function:

loadDefaultTables

?
