I totally agree with Kenny, these new features look awesome, especially the system where you can disallow people to use certain functions when they have a post count lower then a defined number. Previously you needed the Auto Groups MOD for these things. I'm glad to see that RSS feeds are in the new package, very handy for announcements for example. The new CAPTCHA system is quite handy as well, you can now easily add your own CAPTCHA systems, and choose between the ones already installed, makes it a lot harder for the spambot authors.
Lastly, the Quick Reply. I sat here laughing on my chair, because of all the discussion that has been on this before, and people running away when there was someone asking for it, creating a whole discussion. But I'm happy for the ones who wanted it, that it's in. I think that this is a fair way to implant the Quick Reply, because it's manageable per forum and turned off by default.
