My Small vBulletin 4 CMS Review

I was at a friends house yesterday and he let me play with his vBulletin-CMS admin-panel. I must say that it wasn’t really what I was expecting. I’m glad I tried it out before I did buy it.
The style-manager didn’t work as I expected. I thought I was going to choose colors with ease from the color-panel and then just push a button to save it but it turn out the color-panel was just for reference. And I have to use the find and replace tool to search and replace in all files… (?)

I asked him how to edit the mainpage so I could have my forum there and not any articles and he didn’t know.
I looked myself but couldn’t find the option to change it. How do I change the mainpage?
I’m sorry to say that I dont really see the advantage of vBulletin over free forum-scripts like MyBB, SMF or PHPBB (The new version of PHPBB is much better than the old ones…)
It was not what I was expecting at all.
So why would I pay to use vBulletin over other free forum-scripts? I dont know. They’re just as good in my opinion.
