Showing collections is a great way to find some people, able to confirm stuff about a release etc. (MBS-3447).

However, we currently don't know who owns a said collection.
See this release page's collection tab for instance : 2×My Collection.

Some genius people then got the idea of putting their names in collection's name (see 2 genius here). → But that leads to a risk of people impersonation (like if I create a full-of-crap collection and call it YourNameHere's BEST LECORDS EVAR.

So I think it would be a good idea to show user name both in release page's collection tab and in collection page itself (MBS-942).
