I think inception's head gm does it through some gm system idk about.On there you donate for a certain amount of crystals, exchange those crystals at an npc for a "same sex marriage item". With that item you mail it to their head gm with the name of the other character you want to marry and he does the rest from there
Storm did it too and quite often for free. You just had to a request in with you and your spouses acc name and which chars you wanted married. Not hard to do tbh. Don't see why we don't have the option.
Yea cause I got like 10 dudes lined up that I wanna marry
