Comment 2 for bug 28477

After reading https://wiki.launchpad.canonical.com/PeopleMerge, this seems a more appropriate text:

"To merge two Launchpad accounts, you must be logged in on Launchpad, and have access to the e-mail address registered under the duplicated account. Once you’ve proven that you own the duplicated account's e-mail address, it will be assigned to you, along with everything else owned by the duplicated account."
