Thanks for many kind advise.

Well, it's about manage problem but someone knows how to change
moderators name colour in BBS ?

I've changed config.cgi

use constant CAPPED_TRIPS => ('!hogehoge'=>'<font color=#FF0000>★webmaster</font>');

but after I made a change, it turned out rest of all messages
changed to red color which I did not meant to.

All I need to change is webmaster and moderators name color as to
show users know I am the real manageing person.

If someone knows how to modifiy the program please advise.
Thank you so much.
