I love wedding wire. Whilst I don't get a ton of leads from wedding wire I have found their vendor services to be fantastic. I have excellent SEO search results so I don't need WW to find me leads - however their review functions are great and the client sites and the ability to send contracts and questionnaires etc are fantastic.
I read a little about people complaining about the reviews... I haven't had a problem. I find that if you do your job well then people only give you good reviews anyway!
