it is something i've always done for myself on every *legit* co. i invest in .. which would include expo .. but then i always do my own DD on a consistent and ongoing basis and buy or add shares accordingly
i've never claimed to have *expertise* in any area outside of sales and marketing .. which i do consider myself to have *expertise* .. in
if expo's mgmt contacts me for that *expertise* i'll be sure to keep this venue updated ;-)
gotta say .. i'm not expecting that to happen .. X-D
