I’ve added a calendar for motorcycle events such as rallies, shows, etc. in the upper right of the page, above the Blog list. When you click on the link, the calendar will open in a new window. Anyone can add events to the calendar. Since the calendar is by google, it is linked to your Gmail account. You can actually add to it without logging into Four Riders, but you will need to log into Gmail.
If anyone has suggestions or ideas about useability or adding features to the blog, please let me know. Sometime in the future I may move the blog to a WordPress hosting. WordPress has a lot more customization features than Blogger.
