Hey Ray,
One of the priorities of the new team is to give the HMN website some TLC, improving any areas that are a bit rough around the edges, so your feedback is appreciated.
Adding external links and icons for Discord (and any other popular services people may want to link to) sounds like a very sensible idea and hopefully should not be too hard to implement.
I also agree that the license mechanism seems a bit tacked-on currently. It would be nice to add something akin to GitHub's license pages that break down the main points of a license, perhaps along with searching / filtering projects by license. Changing this stuff around will probably take a bit more engineering effort, but would be a welcome medium/longer-term improvement.
I'll add all 3 of your points to our internal notes.
