Re: NIKHA PROCEDURES
it can be done anywhere. usually the guys go to the masjid, and one of the guardians of teh girl gets the permission from the girl to say the yes. then at the masjid there is a khutba, where the molvi usually outlines the rights and responsibilities of the wife and husband. and then he asks the yes from the groom, says out loud what are the conditions and the haq meher, and then the paper signing.
on the other hand, the girl and the guy can be in the same room, same procedure but this time the girl says it herself yes. or they could be in separate rooms (ie if you are in a wedding hall) and the molvi starts with the groom, then goes the the room the girl is in, gets her yes, paper signing, and then a big round of hugs and mubarak bads.
You forgot the mitaaei part ... :D
