The normal color for visited links since the very early days of the web have always been dark blue/purple, while not visited links are a lighter blue color. Anyone who uses the web on a regular basis is aware of this. Some sites do change the link colors, but almost always follow the convention of making visited links *darker* than not visited links. Many Snitz Forum installations have this exactly reversed (including this one) which causes a lot of confusion for users.
It's ok to use different colors for links if it's a necessary part of the design of a site, but choosing to purposely do it
exactly backwards seems to be intentionally misleading for users and is endlessly frustrating.
A couple references about this...

"Your visitors already know from experience that blue stands for an unvisited link, so, if they can fall back on this knowledge when they come to your site, you give them one less usability hurdle."
Please, please change fix the default color scheme. Obviously they were accidentally mixed up when the scheme was first created, and no one has taken the time to fix this usability issue. Usability is important, please take the time to fix this.
