I've decided to put the forum on ice for the time being: Not necessarily closing it altogether, but removing most of the links to it from my website and stop visiting it regularly.

To have a quality forum, you need visitors and coherent subject material to discuss. It's obvious that I don't have the former (some days, I only get two or three hits on the index page of my site itself!), and it's inconclusive if I have the latter.

The forum's still here if you want to use it, and I may take it out of the freezer and "relaunch" it in the future if I see that there would be a need to do so (such as an explosion in visitors and resultant feedback). But for now, it's essentially reached its finis.
