My first thoughts after upgrading dev site to 4.0
 

• Wow* this went smooth.
• ***** they weren't joking about the styles not working.
• The new attachments system is un-****ing-believable. EXACTLY what I needed.
• The new calendar setup is beautiful.
• Can I move threads to articles? Holy **** I can. ****ing-A!
• The new profile layout is sweet. Wish there was a tab or direct link to the user's blog.
• How the hell do I add tabs to the menu (Home* Forum* Blogs* What's New?* ADD ONE HERE)?
• Damn it sure seems faster.

That's it for now. I'm kinda overwhelmed right now with stuff to fix/change/replace/etc. But I have to say* this is pretty freaking sweet. I was very skeptical at first* but this beta release convinced me. This will definitely be worth the money.
