I do care and will help
as we are one the same, if you look...
sorry for the later reply....
Ok problem with the user name change is it is also stored for security in Xoops...
As having main user name's showing and actual names is for the password also and name....
In XOOPS 2.2.5rc2 it is more functional in terms of Admin for users and additional multiple fields (~There Was Many Problems to begin with new ideas, yet works ok now).....
There are new modules to fill in these gap's of 2.2 additional user support in admin ....
Yet still only letting people change their display name in it....which for the most is what you need.....
As if you got someone manage to cross refrence names and passwprd, they could change untill they get in....
When XOOPS registers it also checks for user names in use....
Unsure how much it does if names are changed, as you would need a new process to check at the time, if the name is in use....
I do this by going into the MySql Admin and changing the one's needed....
It is far safer and then only Admin has control....
Yet for display names like you see on most things in 2.2.5rc2, that can be changed by the day by end user.....
Have a look around our site and you can see which modules display a display name and which user name....
Anyways even with Capitals we Care
