Frank Karlitschek was kind enough to add an additional section on kde-files.org for Tellico Entry Templates. I've uploaded three right now, one that modifies the default Fancy template to show two columns of fields, one based on Amarok's reinhardt theme, and one that uses a CSS template from Roger Johansson.
The templates go in $HOME/.kde/share/apps/tellico/entry-templates/ which you may have to create. Don't forget to uncompress the tarballs.
The next version of Tellico will include KNewStuff support for downloading and installing these templates directly.
