mb21 is a personal site run by Mike Brown.
If you want to contact me for some reason, please read this first:

• mb21 is not a broadcaster or broadcasting company
• I do not work for Ceefax, Teletext or any  other broadcasting company
• I have no direct connection with Ceefax, Teletext or any broadcasting organisation
• I am not responsible for broadcasting policies
• If you want to ask a question about any aspect of teletext, please don't write to me, join the Teletext Chat mailing list and ask it there
• I cannot find or book you a holiday!

I make these points explicitly because a surprising number of people waste their time - and mine - by writing to me about matters with which I have no involvement or influence. So... if you write to me about anything like that I will either ignore you or write back to let you know how silly you are! But my bark is much worse than my bite...
