Each region currently has a separate simulator on our grid server and the region managers have the same surnames as the regions so that you can easily find them!
Alternatively, you can contact them all in-world (including by off-line IM). You can also get in touch with the grid managers by leaving a note via their postbox (or dropping a notecard in it if you are old school) by the Welcome Centre on Annwfn, the grid's home region (pronounced Eng. An-oo-vuhn, X-SAMPA /an'uv@n/).
Please report any issues arising, whatever they may be: technical, regarding rules and conduct etc. We aim to answer enquiries promptly.
Come and say hello! :-)
