I'm sure someone has vetted this question before, and after already having tried to convert to multisite (and created a ton of problems that Ipstenu-DH bailed me out on), I figure I'd ask for opinion before I mess everything up again.
I am trying to create two separate micro sites and i'd like to set them up as subdomains. One of them I want to be semi-private (I don't mind if random people see it, I just want to tell a small audience the subdomain URL and have them go there directly...I won't provide links to it on our main site). The other one, I will likely build links to once all the content is there.
For example: women.mysite.com (for a semi-private women's initiative) and impactinvesting.mysite.com (what I want to build links to from our main site)
My question is: do I need to establish a multi-site to achieve this?
I'd prefer keeping it a single site, but I also want to use different themes for each microsite, as they serve very different purposes.
Any advice is very warmly welcomed and much appreciated! Thanks so much in advance.
