Interesting - I have bought seeds from Mauro for a few years with very good results although I didn't buy anything this year because I knew I would be busy and cut down on my seed raising a bit. I see that it's not directly visible from brazilplants.com, there don't appear to be links to the club.html page and I also see it says that it was written in 2007 but there is no 'current' date, so is it current ? I must admit I was going to drop him an email to see how he's doing so I might ask.
Certainly it's not a bad idea for him although as with all of these 'clubs' there is always the risk that the members get seeds etc. that they may not really want. But I don't envy anyone trying to make money out of any international trade at the moment - much too susceptible to currency fluctuations and general recessions and I can see that anything that gives a regular and extended cash flow would be very welcome. I think that a lot of people in that line of business have suffered in recent years with the recessions in their traditional markets in the north of the planet.
The web site has his name as "Mauro Peixoto"
