My ultimate goal of my website is to allow Fitness Instructors from anywhere in the United States to create a profile and schedule a fitness class in their area so my consumer members can attend that class.
My current website is a local website for one city. Even the name is specific to my city AustinFitnessOptions.com.
But, I'm just testing the market and doing a proof of concept stage, that's why I'm starting it locally in my city of Austin. Once I get the Austin market participating, I'll want to expand into other cities (markets).
At that point, I'll want a national brand name, like FitnessOptions.com for example. And from there, my consumer members will have access to any fitness class (in any city) on my website.
So, my question is: what is a "multisite"? And, do I need a multisite concept for my model?
Or, would i use one website and just have different categories (cities) and sub categories (types of fitness options)?
Or, would I use buddypress and use "groups" as cities??
What's the best way to do this? I don't quite know the differences and uses of buddypress, vs multisite, vs categories/subcats/groups/etc.
