The logo and club name on the Race Report is controlled by the Club Info settings on the General Config Screen.

The overall appearance of the Race Report is controlled by the race.xsl file located in the reports directory. If you are familiar with HTML and CSS and you change the colors, appearance and layout of new reports by modifying this file. It is a text file so any text editor can be used. The race.xsl file only applies to new reports, if it is changed existing reports will have to be regenerated.
