Congratulations Nikki, hope all works out well.
I have been married for not quite a month (29th December 2005) and it is great... thus far (

). You're right tho - I have been living with my wife for a couple of years, and all that is changed so far is the way I introduce her - still get a kick outta calling her my wife.
And as far as all the planning goes - if it does give you headaches, like ours did, just remember that the day itself will be great. Mine was, and I have a lot of memories.
Enjoy your engagement, and keep us up to date about the date and how it is all going. Again, congrats.
Ratt.
