Just wanted to mention some updates here.
Thanks to the Merciful dev, we now have Merciful working with the game. It should be compatible with Chrome and Opera.
Orchil has been updated to the newest version as well. If you are seeing Orchil oddities, such as commands being shown in the incorrect order, try clearing your cache and restarting. And although a bit clunky, it also supports macros (a big deal here with hunting).
And Zealotry is still supported, but will require an older browser (Pale Moon).
