Many thanks for all the, er, thanks. I'm pleased the new look is well liked.
Having spoken to a few people last night I realised that I probably didn't make it clear why this change came about - it wasn't a whim - the place I have hosted the site for the last nine years was shutting the service down, so I needed to move to a new company. As the old board software is outdated and no longer supported by the people that make it, it made sense to use the latest version. There is a straightforward process for converting the old boards to this new style, but unfortunately due to the ancient nature of the old server, it wasn't possible to back up the old boards to bring them over.
So it wasn't something that happened because I felt like it, it was that or no site at all in a fortnight when the old server gets bodily thrown out the window. As said, when that does happen, the old .net address will bring you here instead - which is why no links/banners etc have been changed.
