Ok, I updated the zip in the first post in this thread with the fixex for everything so far except the greeting menu.
I added a menuitems compatible mod file.
I fixed the alignment link for OACR when the register link is missing.
I added an option to show/hide the Register buttons for admins.
I fixed the bug with logging out for people who disslow guests from doing anything but logging in. (All mod files)
As for making modifications to the greeting menu, I'm not going to mess with that. OACR Automaticly removes the register link from this greeting when its enabled. There are about 15 other mods that modify this yabb tag as well. So to avoid problems later I'll just leave it alone.
If you'd like to edit the greeting menu yourself simply search for the yyuname tag in subs.pl and edit it to your liking.
Exact code to search for with a fresh yabb installed:
$yyuname = $username eq 'Guest' ? qq~$txt{'248'} $txt{'28'}. $txt{'249'} <a href="$cgi;action=login">$txt{'34'}</a> $txt{'377'} <a href="$cgi;action=register">$txt{'97'}</a>.~ : qq~$txt{'247'} $realname, ~ ;
The $txt{'#'}'s are defined in the language file.
Exact code to search for with OCAR installed:
$yyuname = qq~$txt{'248'} $txt{'28'}. $txt{'249'} <a href="$cgi;action=login">$txt{'34'}</a>~;
If you need a little more help then that, I'm me.
