You could try finishing the singleplayer entry and since enemies are normally unique to just singleplayer, ppl may go there to look.

Or you could make a multiplayer entry and since enemies are very rare there and only achievable by MCEs, which some ppl have never heard of, and link the enemies page from there.

EDIT: But, if you start from the J2o main page, it only takes 3 clicks (from the quick links) to get to the Enemies page. It's not that bad. If ppl can't find the enemies entry, then maybe ppl can't find other entries like battle or JCS events. Maybe there should be a sort of guide to 'users' as well as 'writers' of the ERE?
