Pretty sure we have a Tractatus on teaching 
not really keen no.
Anyway, I believe I've promissed to spend my private points by the end of the weekend:
Key to Safety - 20 points.
This will be mainly for lab use (+2 safety, +1 experimentation), but I'll probably bring it along when I travel.
The Tireless Servant (Cov, p. 121, box) - 16 points
Lab: +1 Safety, +1 General Quality
Mirror enchanted with The Endless Repetition in a Bottomless Pool (Cov, p. 101).
- which I trust we can all agree isn't much worry with regards to the code, as it only scries on books.
Lab: +3 texts. Will hopefully be integrated as a feature at some point.
All of the above are high enough level that they are probably invested items, with empty 'slots', and I do plan to makes notes on this, but not right now as it's passed midnight local time 
OR: Can we buy vis sources with the private points?
