Group Chat issue on WoWonder

The group chat seems to be having a basic issue. Silly treatment of this issue !!!. This is one essential and very important logical issue: searching for users only by using a ‘username’. We are talking about User Experience !

At ‘creating new group’ on CHAT – when looking at the search for other participants, we can find them only by their ‘usernames’ but not by ‘name’ (actual name).

We don't know how to identify or search for users by using a ‘username’ – especially some have strange and unclear usernames – and we usually remember to search for people only by their ‘name’.
So, in my opinion, it should be possible to enable it also by ‘names’ /or ‘usernames’, together,  just like it already exists on the general search in the header area of the home page.

It makes sense and sould be fixed,

Is somebody knows how to fix that?
