I wanted to add the following plugins to roundcube but didn't know if they would work or interfere with ISPC3 in any way.
Password change: http://trac.roundcube.net/browser/trunk/plugins/password
Managesieve which does vacation notices I think: http://trac.roundcube.net/browser/trunk/plugins/managesieve
I know we have those in ISPC3, but I wanted to hand control to my users.
any thoughts would be appreciated.
