Highway:
I had a look at this earlier but just as i went to upload the first file the server decided to start playing Hide-n-Seek and its a damn sight better at Hiding than i am at Seeking it
I told DW to go find all cases of ' {USERNAME_FULL} ' and it retuned nothing, but i have got a few cases of:
{memberrow.USERNAME_FULL}
{admin.USERNAME_FULL}
{mod.USERNAME_FULL}
I've replaced those with the line you mentioned but see no changes.
The documents containing 'USERNAME_FULL' in the code are:
mcp_warn_front.html (twice - 'highest.USERNAME_FULL' and 'latest.USERNAME_FULL')
mcp_warn_list.html
memberlist_body.html
memberlist_leaders.html (twice - 'admin.USERNAME_FULL' & 'mod.USERNAME_FULL')
ucp_header.html (twice - 'friends_online.USERNAME_FULL' & 'friends_offline.USERNAME_FULL')
Admittedly I've only modified the memberlist_* files because i felt i'd see the change straight away there, however even then i dont see how this could fix them appearing bold on the thread index pages. Its the name against the latest post in that thread and similar cases which i dont like, these just appear to possibly modify the memberlist and control panel pages.
Is there something I could be missing? And why isnt this modifiable in a simple manner, css or by group management? Maybe some people dont see it as an eyesore, but for a small 'clan'

forum like ours where 75% of the activity is by people in a locked usergroup we dont wish to stand out like a small group of Moderators and an Admin might wish to make themselves fairly visable. I just need to be able to modify the privilages of the members in that group as a whole rather than singularly.
If this cant be fixed then the only option i can think of is to make sure my members stay as a 'registered user' as their primary group so they're not stalked by the bold coloured usernames, i'd imagine they'd still have special usergroup rights though which is the only saving grace really, specially coloured usernames is fine, bold just feel rather vulgar to me (IMO).
