Translations:Plugin:Dummy/3/en
It is useful when some protocol became deprecated (like Skype or XFire) and you want to preserve history of your contacts. You can "upgrade" your old account to a Dummy protocol and then use your contacts as before (showing history and user details, except communicating with them, of course). Also you can make a metacontact from this dummy contact and merge it with contact on different protocol to have complete history available from single contact.
