Using the Internet Archive Wayback Machine, the last post on oozak.com was on May 9th 2021 announcing that he expected a new format of Oozak would be up and running by the end of May. I've not been able to find a new Oozak. The 2021 messages prior to May 9th announced a warehouse clearance sale where 'everything must go'.
I really liked Oozak back in the day when I bought a lot of supplies. I wish Rusty the best, times are hard.
Here's a link if you'd like to check it out:
