I have re-enabled the forum.
I was forced to disable it some time ago due to the large number of bogus users attempting to spam the forums using sophisticated software which apparently can get round the requirement to type in the contents of a visual image in order to register. This was taking up too much of my time to weed out these applications.
Anyway, we'll see how things progress. Please, as a genuine user, let me know if you find this forum useful by replying to this post.
