If you’re like me, you forget about certain sites. There are just so many out there these days. You can subscribe to updates on this forum on a per-category basis on this forum. Just go to the category page (The “General Electronics” one is a good candidate) and change the notifications
For the one that’s shown highlighted, I get an email every time there’s a new topic or reply. That’s likely a bit too much for most people, but also a good way to keep up to date.
You can turn these on or off at any time.
For course members
Doing the same for the Projects forum posts and the Skills forum posts will let you know when there is new content published on the main course site, because there will be a corresponding post on the forum. These new posts are hidden from the front page, so it’s a good idea to get notified when there’s new content.
