Solar fans will be happy to see (as mentioned in the latest post from Paul Jones) that all of the previous (and future) posts he's been making as tutorials on certain parts of the framework have been integrated into the Solar manual.   The translation went pretty quickly, because I wrote the original blog entries using Solar_Markdown, which converted them to HTML for the blog. Then I did some quick edits and re-converted them using Solar_Markdown_Wiki (which is the markup format for all the class API and manual entries at the Solar website).   Posts adapted so far include the posts covering views and layouts, using HTTP and sending email from Solar.
