I know there is no such thing as best, it will always depend on the situation.
But anyway, in my opinion a basic community has content management, forum and picture gallery.
I have created sites using Mambo CMS and integrating it with Vbulletin forum. Works great.
I also wanted to have a picture gallery.
But it is always difficult to find a CMS solution that ha sa good integration with a forum and a picture gallery.
It seems that the new Gallery (by menalto) will integrate well with Mambo. But then, I still need to integrate with a forum.
Any suggestions on complete solutions or easy to integrate?
