GHacks.net posted a guide about syncing Evolution contacts with UbuntuOne
How many machines do you have? How many contacts do you have? How many machines do you try to keep your contacts in sync on? There are a lot of ways to do this. You could copy those contacts on a flash drive and move them back and forth, making sure you add the new ones when you make any changes. But that is far more complicated than it need be. OR you can use a contact syncing tool to make this process automatic.Sync your Evolution contacts with UbuntuOne
One such tool for Ubuntu Linux is Ubuntu One. UbuntuOne is not just a music store or a means to sync pictures and music. With UbuntuOne you can also keep your contacts in sync. This is especially easy when you are using Evolution (there is something to be said about using the default applications). In this article I am going to show you how you can keep your Evolution contacts in sync with UbuntuOne so you can use those same contacts on any Evolution groupware suite that happens to be connected to your UbuntuOne account.
