I've just logged in. Well, strictly speaking I went in to Seagulls Tickets and found out I was still logged in from yesterday, though I was then presented with the logon box anyway. Anyhoo, it's pretty clear from the summary page on your account that you can assign tickets to your friends and family when buying them yourself but that anyone marked with a star is a special friend who can buy for you.
Although now I've typed that out it seems as clear as mud.
