Hi-

I want to change the title of a member profile page so it shows their full name instead of their registered user name.

So if they registered as "SSmith" and their full name is "Scott Smith", their profile page would say "Scott Smith's Profile" instead of "SSmith's Profile".

Is this simply a field display change and what file is it located in? Tnks.

Go to the configuration screen in Community Builder.
In the general tab, choose the name format as Name Only.
This will do the job for you.

Thanks Neo
