I have several young cousins that will be ending their college semester right as my invites will go out. They will likely be moving around for the summer, and may not get an invite that is sent to a previous address, or an address they only are at during the school year. I was thinking about just sending invites to their parent's house. Or I was thinking about giving the option of an E-Invite for people that are moving around. I was thinking this may even be better for friends of mine that move regularly. I got about 5 STDs returned, and it turns out people moved between the time they gave me their address and the time I sent them out (6 weeks!). Thoughts on the E-Invite option? I would also give a paper option if I can get a solid address.
