I have spent some time today upgrading the forum software to the latest version.
This brings a number of enhancements, mostly behind-the-scenes, and a few new features for registered users of the forum. These include the ability to edit posts you have previously made.
One side-effect of the upgrade is that the script that displayed the last five posts on the front page of the website no longer works, and no amount of tweaking would pursuade it to function properly again, so this feature has been temporarily withdrawn.
I have checked through everything and as far as I can see it is working, but if you notice anything that doesn't work as it should, or as it did previously, please let me know!
