Junk mail and privacy - one you probably don't like and the other you strive to achieve. If you want to avoid junk mail streaming into your personal email account and keep those accounts private from guests you may not know that well (i.e. - colleagues of your parents), I suggest you set up a new email address for wedding planning.
I am happy to pass along some very exciting news – IKEA now offers an online registry!!! You can use this for any of your life stages from getting married to having your first baby to a housewarming party to just keeping a running list of things your family can get you for holidays, birthdays, etc.
A lot of people will tell you that wedding programs are unnecessary. But have you ever been to a wedding without them? I am annoyed because I want to know who the lovely people are that they've decided are so important to them to include in their wedding party. Plus, who doesn't like knowing just how long (or short) the ceremony is going to be?
