I am running a Multisite network. I use themes from Elegant themes for my users. However without a theme demo users are finding it difficult. I wanted to
1. Set up a sub-domain like demo.mainsite.com/theme1
My doubt here is, if there are 80 themes,so should I install WordPress for 80 times? Like each installation for each theme. Is there any other way? How do theme company's host their demos?
2. How can I have theme switchers like found in elegant theme demo themes?
3. What About SEO? Should I No-index or No-follow or both?
4. For creating theme demo site, where can I find free images? can I use those images found in Original theme demo?
