Since marriage will be allowed, there needs to be actions that will be specific only to married couples.
/cuddle
/hug
/give flowers
/massage
/whoo hooo (in shower, on couch, on bed, on any outdoor furniture like hammock)
I also, do not think just anyone can get married. I think that there first has to be a courtship - you register somewhere, and then you need to LEVEL-UP your relatationship before you can get a marriage license.
There will be a /join couple action, then the two of you would level-up the relationship, by doing certain quests. Also, need to do a quest where you get blessed by some goddess or other.
Perhaps when you reach a certain Level in the Relationship Quest, you can /woohoo if you reached soulmate status.
Status in Relationship quest:
Level 1-5 good friends
Level 6-10 Best friends
Level 11-15 Friends with benefits (woo hoo)
Level 15 - ..... Soul Mates can get engaged
Level .... Can get married
And of course a Marriage Help Manual with pictures
I started a thread on Lodestone.
