Hi Ricky,
We should have a new release out next week with the SuperFlexi Folder Multi-Tenancy issue fixed. We have it running in production on two sites right now, we just need to finish some testing of other changes and then package everything up.
To change to Hostname Multi-Tenancy, set the following in your user.config and then touch your web.config:
<add key="UseFoldersInsteadOfHostnamesForMultipleSites" value="false" />
Once that is set, you can use the documentation here.
Thanks,
Joe
