It's cost prohibitive (when legal) to send plants (or any package) across country lines. I'm sure that's the reason the exchange is limited to US, along with the amount of time plants would spend in a box. Probably not worth it for that reason even if there wasn't a legal hurdle to cross.

I bet a UK swap would be a big hit since there are a lot of forum readers from there. Nothing stopping you from getting it going. I've arranged/hosted a couple, would be happy to give you some tips.

Well it wouldn't cost that much to send as it would from america to england. Mind you I have received plants from Turkey and even Australia!
By the way, does anyone know of a lady from Turkey on here? Shes who I got my big Aloe from way back when...

No doubt. Does it actually prevent you from posting? I don't think anyone would mind if you did and just made it clear you're in UK.

greenlarry - there is a UK GW forum but it's pretty dead. I just Googled 'UK plant swap' and got a lot of hits. There's one at the link just as an example. I know nothing about it so can't say if it's any good.

GW is basically a US outfit so I'm not surprised there's isn't a UK exchange. The red tape and cost involved in shipping across international boundaries makes it difficult. But these things are not just there to annoy us. There is a history of disasters caused by shipping plant material between countries. Dutch Elm disease? Lily Beetle? Sudden oak death? Ash die back? And on and on. All caused by infected plant material being imported.

When I flew into Boston they confiscated an apple I was intending to eat on the airport bus. Too dangerous!
