Re: [PSUBS-MAILIST] Some questions

["Pierre Poulin" <pipo305@hotmail.com>]

Hey, nice writing Warren!

It's good for the morale to read that kind of stuff. I must confess that i'm 
building my sub with some degree of secrecy. Just tired of hearing: you 
gonna kill yourself with that, that thing is gonna sink! (isn't it the 
point?), Hey, nice coffin! etc... So when I shop for a valve or something 
else, It is always for a swimming pool...

I don't know why i'm writing this, but it make me feel good, sorry.
