Prior to joining the Canadian site, I was on the US version of Wedding Wire, which allows brides to add other contributors. I don't see that option anywhere here, other than the Linked Accounts option - is that how it works here? I loved having my mom, mother-in-law (to be) and fiance on here to help add people to the guest list, check things off and generally contribute to the whole process.
Looking forward to hearing from you!
