I really don't think you can trade bulbs without some type of license, but I could be wrong.

I doubt if it would be worth the expence to them if you even just sent them for postage. Without the appropriate paperwork, they can be confiscated.

When I get emails from folks that don't seem to have a GW id, the first thing I do, is ask for it, or ask where they got my email address.

I definitely would not trade internationally, unless it was seeds.

Perhaps once they provide a GW id, you could point them in the direction of an appropriate forum for their country/ continent

Thank you both. That was my inclination, but I wanted another opinion.
