Additionally I was thinking about trading, could I register a dwolla account to transfer to/from MtGox and Tradehill, this service is US only at the moment but do they check the address you enter?
Thanks for helping
If you are dealing with small amounts why are you worried about liquidity? Intersango has free trades, free deposits/withdrawals in the UK and they have a considerable volume. It seems like the obvious choice to me. Not everyone is lucky enough to have a bitcoin exchange in their country...
Yeah I trade a lot with GBP on both Gox and Intersango. I'd say go with Intersango definitely. Its plenty liquid enough and tracks the USD price of Gox (the most liquid exchange) very very closely.
