i think a lot of it is what you expect, like what has been said previously.
you say that it's not the wedding that makes you nervous, its the guests. well, the best thing i can say is invite 20 of your closest (and i MEAN closest- the people you'd feel comfortable tellling almost anything to) friends and family. cause they're the ones that love you and they will make you feel comfortable on your big day. then, in order to include everyone, have a big celebration party later that day/week for everyone! that way, the emphasis isn't on the fact that you're getting married, but on the fact that you ARE married. that's what martel and i did. i really like the idea of getting married with family and 2 friends at the parent's house, then having a big BBQ in the backyard for everyone. mainly, remember that this whole "wedding" thing is there to MAKE OTHER PEOPLE MONEY. the only reason we have a wedding ceremony that's all big and elaborate is because some queen back in the day decided it'd be a good idea. maybe look into non-traditional wedding ceremonies, like indian or irish. if religion isn't an issue, go with what feels best for you AND your fiancee`- don't leave him totally out! communicate with each other, and don't freak.
