Hi, Sneezecakesmum! I was on the BBC TA MB too. The BBC decided to close it down as a cost-saving measure. They push people towards Twitter, Facebook and their own blog. The blog gets a handful of posts a week, in marked contrast to the old MB which was vv popular. However, I found that latterly it was also vv negative about TA, full of nitpicking about details, and I didn't enjoy reading it so much any more. I love the MN threads as I think we are all on the same sort of wavelength about TA.
If you did want to catch up with other TA fans in a dedicated forum, there are at least two:
This is Peet's place: started by a technically minded TA fan many years ago.
[[http://mustardland.boards.net/ This is another board set up by a woman who used to use the BBC board (Sue?).
I don't use either of them but they seem to have a reasonable amount of traffic.
The Archers Addicts had a messageboard for some years, but that seems to be defunct now - I think they may rely on Facebook instead. It was never heavily used. I looked at it a few times but found it much too twee and cosy for my taste.
There may be others, but I find this thread is just the ticket for me!
