I have to create a simple network of websites (different sub-domains) using WordPress. There are just going to be 3 or 4 such websites.
I know that WordPress MU was integrated directly within WordPress 3.0 and I can create a Network and use it.
Are there any pitfalls or disadvantages that I should be aware of if I go for this route?
Or, generally what are your thoughts on WP 3 Networks?
