All i have to say is Sitecore Version 6 is even better then the previous. I've been using Sitecore now since version 4 and version 6 is just another great product. Not only is it faster to use but also to develop, the current ubeeTech site is build on version 6.
Some things to note about version 6:
- Improved UI
- Faster response times about 400%
- Improved Security using the .net 2.0 security
- Fewer databases (which is a good thing i think)
- Improvements to the Sitecore SheerUI which now makes this administration system in its own league for speed and usability.
I'll be posting some code and tips later on so just stay tuned my friends.
