Re: Content Management - Which one
your first q, cms
offcourse joomla is best, because mambo is no more and phpNuke is not that populer
I knew another simple asp.net based CMS (Dotnetnuke) but it is not that populer like joomla, but it is easier for end-user.
about template.
There are hundreds of free templates available online, why don’t you get that?
I can create a joomla template, but first thing
- it will take a lot of time and it will be painful when I will not get paid
- may be it will not be of your choice, because I can’t show you the preview first
so my idea, go to some site and download any template with preview
I dont know you will like to take an illegal one or not
But I have hundreds of templates downloaded, that are illegal 
I can recomend you 1 site
check out this free template, I hope you will like it.
