Thanks very much.
I do wish it was easier to find information on the BT web site. I was reading about the Broadband usage meter on another thread as this seems to have disappeared from my services page. Whilst this answered the question of where to find it I was unable to find this via the page search engine.
Thanks once again.
BT can make it difficult to find things. Luckily many of the customers on this forum can usually find the answer
