I'm sure this has been asked before but I couldn't find it when I did a search anyways what I want to do is be able to edit my Display Name directly from the main contact window without going to the options just like you can do with the Personal Message. I know before a long time ago I was able to do this with plus or something else but I don't remeber what. Anyways if someone has the answer would be appreciated btw I'm using the latest version of WLM 9 with plus and it works great
