So, I wasn't sure how to handle the whole "wedding website URL on our invites" issue because I'm cheap and just use the free Knot page which has the ridiculously long address. I was going through my links today and found the perfect solution which is better than TinyURL because it allows you to CHOOSE what your end result will be. The site is
http://tinyarro.ws/ and they also have options on there like a heart, flower, or star as part of the URL. (no good for printed invites because not enough people know how to type those on their computer, but perfect for e-mailed or online invites)
