My wedding is in 4 months. Let your woman plan the whole thing and always help when she asks. My responsibility was to plan our honeymoon but I did booked venue, dj, photographer, and limo. The first thing you need to do is to set your budget and attend wedding expos. Remember, wedding is mostly for the wifey to be... Also, do not go crazy... wedding lasts only 4-6 hours. Not worth spending all your life savings on it.
this (plus what panthro said)
went to a wedding this summer for a cousin, who's now in-laws took out a second mortgage on their house to pay for the wedding... which was so completely over the top and retarded that nobody really had any fun (nobody really likes the wife tho, so that didn't help)
all of our family constantly reminds us that our wedding was amazing - we had about 50 people, didn't do most of the traditional stuff and just made sure we had really good food and REALLY good music. a band >>>>>>>>>>>>>>>>>> DJ
