I plan on opening a tutorial site based around photoshop. Will i get more $$ from it being a blog or forum? Im not just interested in the $$ so what are the pro's and con's of each? Thanks.
For this kind of content I think a website would be better. However a forum would be better than a blog if you had to choose between those two.
IMHO, I think a blog would be easier to navigate. A forum just wouldn't seem right for something like this.
You should probably start a normal website: not a blog, not a forum, but a website with Joomla or whatever. Then, you can add a blog (WP or the one built into Joomla), and when you see you have a nice amount of visitors, you can add a forum. Nothing keeps visitors away like an empty forum.
I don't have any idea about Xippy! Yes! Joomla is FREE! http://www.joomla.org/ Demo: http://demo.joomla.org/
Oh, and there are TONS of templates for Joomla... hundreds of thousands, if not millions! Maybe I'm exaggerating...
