the moderator has been offline too long

If you want, you can contact the SRC mods to give you admin access over the board. The general rule is that you have submitted about 3 weeks in advance and not received a reply, and attempted to contact the moderator through other avenues to gain access.

To do so, you would want to click Support at the top, create a new ticket, and select "moderator for an existing game". I haven't used the new system personally but that should work!
