One of the major oversights in my initial design of SAFARI (my site's blogware) is that it could only show one page per category. So, given that each category shows the 10 most recent posts, anything older than the 10 most recent posts vanished. Now, I've added a search engine style bar to the top of every category page (including the front page) allowing you to move through all six and a half years of asisaid content, not just the most recent postings.
The new navigation tool is probably alpha grade, and I'd appreciate any reports of bugs you notice, but overall I think it is working well. Give it a whirl and let me know how it goes.
