Thanks for the offers!!
Most of the work consists in double checking suggested plants for whatever criteria we set (ex: height, temperature) and then checking that the plant can be found in the USA, EU (and Canada if people join) and also below our price limit (usually 20 dollars/euros). The first part is 'easy' to do using the IOSPE website and/or Orchidwiz, but researching availability does take a a lot of time, since dozens of vendors must be checked. As we approach the voting stages, if certain plants are only available at one grower, then they need to be contacted to check how much they have in stock.
When Rosie and I did a project together we had divided the list, so it was more manageable. Since that worked really well, ideally it would be nice to have one person volunteer to be my 'partner' and share most of the work, and then other people pitch in when and where they can.
So let me know if that sort of work sounds manageable!
