I've made a few cosmetic changes to my NBBS forum

I've substituted username for fullname where appropriate throughout the forum layout

I'm currently not able to see IN .php code where/how I can
modify the

"x users browsing this Area: aaaaaa, bbbbbb, ccccc"

to show bb_users.fullname rather than bb_users.userid

I'm also not seeing the code to enable fullname to be displayed under
"Board Statistics" in the forum page footer

Does anyone have a pointer to where to modify this in the source?

For reference, I'll post here how I've changed this setting elsewhere in the .php code shortly

Thanks in advance
