Intersango seem to be having problems with their UK bank account (statement says they will be closing it at the end of the month) so perhaps best to wait until they have a solution.

1. Intersango should make this banking issue more prominent on their landing page. Had I not been browsing the forums I would not have come across this.
2. Intersango should post more updates with regards to the issues and progress they have made in this regard.
