I did get your PM earlier but couldn't answer. The offer post has now disappeared and I didn't hear from them so the rails must have gone. Sorry. You might still be lucky as they come up fairly freaquently. I'll keep looking.
I thought as much - what a shame but thank you so much for taking the trouble. I managed to register onto the Tower hamlets site last night and have posted a "wanted" and I've used the Lambeth site before so put one on there too.
