The original link (https://gadgeteer.co.za/rss.xml) was provided by Drupal, and with the recent migration to WordPress, it means that link has changed. However on the plus side, WordPress now does offer three different RSS feeds being Everything, just blog posts, or just site notifications. The feed links are in the sidebar, for easy access.
The site notices would be of interest to anyone about scheduled, or unscheduled, downtime, as well as other key changes or updates. The blog posts are naturally my daily tech and gadget posts I do.
I did put an automatic redirect on the site so that hopefully anyone still using the old RSS feed, should actually continue to receive all posts without interruption.
