I have decided to seperate all of my working genres into seperate entities. So will have a seperate subdomain for each part and leave the root alone.
I am thinking that I wish to do this using the multisite. Now I have a database but it contains all the old posts etc so I am thinking that I just need to delete the database, start afresh and reinstall everything.
So when installing the wordpress theme again how do I make is multisite instead of single?
