I am interested in using tailscale as an individual user.
I'm essentially worthless as a user: I'm a college student and would be unwilling to pay much; I might possibly convert to a serious customer but that would be years and years down the line when everything is different.
I'd also be massively underutilizing it to connect a handful of devices and max two or three users.
I put my email address in your system, and am crossing my fingers.
