The Urchin 4 reporting interface accomodates cobranding (co-branding) and customization by allowing you to create a frame on top of the reporting interface. By default, this frame already exists with a size of zero. To change the size of the frame and create cobranded custom content, you will need to manually edit two files in the distribution. In the folder:
[urchin install dir]/lib/ugroups/default/
You will find:
Using your favorite text editor, change the value in the topsize.html file from zero to the desired height of the cobranded frame in pixels (ie. 50). Then simply add your HTML content to the topframe.html file. This content will then be delivered in a frame on top of the Urchin reporting interface.
NOTE: upgrades may automatically overwrite these files. Be sure to keep a backup copy and then check these after upgrades. To modify the Summary reports, make similar changes within the lib/ugroups/rollup directory.
