It's a multiple post kind of day for me I guess

Can you tell I'm frantically trying to get my invitations out the door, argh!?
What did you guys do about the RD invitations? Did you include a separate card with info. in your invitations or mail it separately? We are inviting about 40 people or so to the dinner, which is roughly a third of our guest list.
Also any creative wording you did for the invitation?
