Different mobile devices would benefit from different portable themes that WorldClient offers. To force a theme for your device, use one of the following URLs:
You can force it to use XHTML by accessing WorldClient with the URL:
http://servername:port/WorldClient.dll?Theme=.XHTML
You can force it to use PocketPC theme by accessing WorldClient with the URL:
http://servername:port/WorldClient.dll?Theme=.PocketPC
Note that as of MDaemon 10.0 and up, you may choose which theme you wish to use at the login screen as well.
