As a noobie, the username / display name issues was unknown to me. If I had know the problems I would encounter, then I certainly would have choosen my username more carefully, as I thought a display name like feature would have been used. Well yes while there is a display name field, very little of supporting software in sl actual shows my display name, it shows in my case Malestorm Resident. When I join a contest, tip a DJ, make a purchace, ... I am constantely seeing Malestorm Resident, event though I have my display name defined. In the case of contests, since what displays over my head does not match what is on the contest boards, it makes it confusing for people to vote for me.
Furtheremore, not even the LL web systems are fully converted. For example, I cannot make comments on the Wik and had trouble asking a support question, because, as it states when I try to login, "Residence with only one name can not log in yet." And I have a premium account.
So from a Noobie perspective, I should hope LL knows that they should not be making their new, paying residents feel like third class citizens.
