I used Roundcube via cpanel. Is there a way to upgrade from the basic level? I would like to customize my signature a bit more because the basic options are quite boring. Also, I'd like to make it so my signature appears at the top of my reply-to messages, rather than having to cut and paste it at the top each time- I've heard getting the upgrade can fix this.
I've tried going to the roundcube website to download but that doesn't work for me. It tries to open in adobe and isn't supported. Any help?
