Hi David,
I mailed Trask directly, and he would like to see more interaction from users (aka other devs).
That is, reviewing PRs would extremely help, as well as picking bugs and creating PRs for them.
I reviewed some bugs and also wrote a mail to some former contributors, who also seem willing to
further contribute.
About the foundation thing… It would have been possible in mid-2020, but now without posts it is much harder.
For example, the ASF only accepts projects with a community as far as I know.
So, the best we can do: advertise / spread word about glowroot and help Trask maintain this software.
Maybe one of us could become co-lead so he is not the only one who can publish releases.
That would be super helpful!
