(continued from a private message thread)
I hope you don't mind that I started this as a new topic? After I started answering your question, I started on a tangent that feels relevant to more than us two.
First, how I found your profile page: I searched the activities for "alex pikkert" and clicked on one of the two activities that is listed under your user name. Once in the "activity", I clicked on the link with your user name where I see 16 inventions and 19 activities. You would know better than me if all your stuff is there. Did you know you are one of the most prolific Bitsters? Also, your documentation is AMAZING.
Whether they find and organize all our inventions or not, I personally am glad for the fresh start. I actually suggested they let my old stuff disappear into the swamp so I could have a clean slate. They were like, "um, no". (Haha, not an accurate quote.) Maybe it's time for a new profile. I can go under cover.
Now for the tangent:
I don't yet understand the activity vs invention terminology. I'm sure more will be revealed in due time.
From what I can glean, an activity has steps and details and an "invention" (or remix) is one bit of media and a small paragraph, which can be posted in response to an activity. On the old platform an activity with a lot of media and steps was indistinguishable from an invention remix with one piece of media and a couple sentences. Also, there was no way to track remixes, give credit for prior work, or know if anyone else looked at your project. Now all that stuff (and more) is possible, which is pretty cool.
