Does anyone know...

how to post their wedding website in the 'community' section?

Thanks!

Click on the top where it says My Account and on the right you'll see My Wedding Website.

Go to my wedding, then wedding website
Click on site configuration...scroll all the way down, ont he bottom it says disable/hide, you might have clicked on it.

ETA: If its a website youcreated somewhere else, it may not let you post. I think it has to be done on here...HTH
