On Cardzilla, we like to keep things fun, that is why private messages travel by pigeons! If you want to thank someone for a postcard, just visit their profile and click Send a pigeon next to their name. A little messenger bird will carry your note straight to them.
If the user is not online, do not worry. Your pigeon will patiently wait and user will get an email notification once it arrives.
To check all your pigeons and conversations, simply click the icon in the main menu at the top of the page.
