John,

That was *fast*. I'll look into moving some of my notes into this.

What do you think regarding the initial setup of "spaced" interval?

Were there a file full of tidbits to digest this way, a way to
pseudo-random scatter them across a few weeks might be useful.

Now I've got to remember my git commands to checkout the latest. ;]

Thanks.

PS. Next time I'll bring my gaming HD and we'll LAN party!
