After working on the project locally for several months, I finally launched Packstack on r/Ultralight.
I had very few expectations as to what the "launch" would bring, but I was blown away by the response. The post had over 200 comments with incredibly detailed feedback from community members. Clearly, this had some interest.
The exposure produced more than 400 sign ups, and many of the initial users have kept coming back. Since the launch, I've added analytics and implemented Mailchimp. I've also created a long backlog of features to build out.
