Class-shmass, just pop by my tent and I'll teach you any time you like. With just the two of us I can probably teach it in a matter of minutes. The only reason it's a 1 hour class is the cat-herding that is organizing and instructing multiple scatter-brained SCA people with no hand-eye co-ordination.

About the mold testing kit... do tell me more. Is it testing for air-borne mold, or just for mold on a surface (which we know is there, I don't need a test for that)? How much do these kits cost? Where does one obtain one?
