WP eBooks, the WordPress (and largely multisite) product site of Ron and Andrea Rennick, whom I like to refer to as the unofficial godparents of WordPress networking, have released a new ebook called Aggregating Global Content. It is available for $17 and is delivered via download upon payment.
According to the product page, the book will:
…show you how to aggregate global content, set up sitewide tags, create a huge tags cloud like the one seen on WordPress.com, and also a bonus tutorial on how to make the default signup page its own specially named page to help stop spammers.
Additional “hidden gems” are promised in the description as well. Real, honest-to-god gems. Perhaps rupees? Diamonds?
Honestly there is just more useful multisite information in there. Which is nice too.
