Super @hamishjohnson, that you made these improvements already! This is exactly why we have created the Apps & Tools category on this forum.
I can’t tell you what is required to be mentioned in the Take Control section of the Center’s website. The HTC operates independently of the CHT, so you should probably reach out via the contact form on humanetech.com to ask.
Community-wise for special cases and larger products / services, we have the Exemplars category (but still have to highlight how we treat these cases).
We are also developing our own Community Website and Awareness Program in which we may start campaigns to promote Time Well Spent softwares (if you want you can join the Campaigners team and help set this up).
Also we have an idea to start a Certification and Logo Program with checklists, guidelines and reviews of appropriate Humane Tech related software and deal out Global Awards (and on the other end of the spectrum we could also create a Hall of Shame).
