Along with the RSS Feeds, there is now a newsletter option on AustCrimeFiction - the link to subscribe is down the bottom of the site, there won't be a lot of newsletters, basically I'll send one when there's been a reasonable number of new posts gone live.
Also, in order to provide a regular update on activities, there's now a single page:
https://www.austcrimefiction.org/last-fortnight-on-austcrime
that lists the last fortnight's updates (blogs), books, and reviews added - it has an RSS feed as well.
This will be the page I'll post out to social media (not the commercial ones), on a regular basis. (You can also find my posts now at https://bsky.app/profile/kcfromaustcrime.bsky.social - I'll add the link to the block at the bottom when I can - it seems there's no FavIcon for it at the moment).
