This is what we do.
The first one to register is asked to choose a subscription for their couple that will ONLY start at the end of the trial period. You can close your account at any time so signing is literally risk-free.
You can do many things there but you will be prompted to invite your partner first. It is a site for couples after all!
Once that is done you can start playing with the site, here is what you can do there:
An email has been sent to your partner immediately after you invited them. This email is important because it contains a specific link to connect to your account and your account only.
Their signup process is even simpler than yours and they can directly access their dashboard where they can do all the things you can do on yours.
NOW though the fun starts! You can see what your partner posts, you can comment and ask questions. You can suggest an impromptu date and discuss live on the chat system.
Whenever you find something you would love, login and post it on your wall. It does not have to be for a specific upcoming event but if it is, make sure you choose this event and add it to your post. Your partner will do the same.
Next time you look for a great gift or you want to surprise your partner you know where to go!
