Setting up a WordPress Multisite install

Looking for some perspective on launching and hosting a WordPress Multisite install.

Is this a highly time and skill intensive undertaking or is it something that can be administated fairly easily once it's set up?

Is there a forum or source of information available on wpmudev that reveals some of the pros and cons of running a new network build on a WordPress Multisite install?

Thanks for any help or advice :slight_smile:
