I changed the theme of my blog by searching through the archives of templates available in WordPress. I decided to go with a neo trendy look to jazz it up a bit. This was the 5th template I selected. The others were too limiting with color and flow. I like the energy of this new template.
Additionally I added some widgets for pages and a calendar.
I also installed the wiki feature
I played around with the colors for backgrounds as well as the text colors trying to find the right combination.
