Hi all,
I am new to RC, and have to say I LOVE it. Grin I am trying to alter a few things and the one I am currently stuck on is showing the email of a user in the header, so the something in the header would be blah@doe-Roundcube Webmail . Does anyone know how I could do this please? Any help would be greatly appreciated. Thanks!
P.S.
It looks like you cannot add php code in skin template file
