Recently active topics in Wuala tagged with real name

Hi WUALA-Team,

I would like to suggest the following helpful function:
when having a lot of firends in WUALA, it is getting difficult to remember the person behind the nickname. Instead of adding a tag to the contact wouldn ́t it be a thing to make the nickname renameable (as you can e.g. in skype) or give the chance to add an additional line which is always apparent to me?
