As of now, also all the aliases to NG work as they should. Apparently I ticked the right boxes this morning

Mail notification should be functional as well.
NG thus can be accessed though nikongear.net, nikongear.com, nikongear.org, with or without any 'www' prefix. The rationale of the aliased sites is two-fold, firstly, they trap existing references to content posted on the 'old' NG, secondly, we can set up diversified services later on.
Besides these aliases, the backdoor approach through fiercebearofthenorth.com works as before.
