The [pascal] BBCode tags were just a mod that we used when running under phpBB, we don't plan on modifying any of the site software's code as it impedes updates and site stability. The [code] tags work just as well however.
One of the nice things about vBulletin compared to phpBB or SMF for example is that you can collapse and expand sections of the Forums so you don't have to see everything at once. Should you close your browser and revisit PGD, you'll notice that the forums will stay organized as you left them. Also What's New is the new 'Posts since last visit'. It also includes News Post comments too.
If you are really keen, you can use an RSS Feed reader to read all the latest forums posts if you like.
As for the formatting tool bar, there is the simple one if you hit quick reply, but if you want more advanced options you should select 'Go Advanced' instead and you can do more to format your post content. Including uploading images and files that will not get lost by referencing external hosting services.
No one likes things to change all the time, but I'm sure you will see that the site now out performs the old one and has many more clean features than any of the previous versions of the site.
