I have a blog (that I call my master blog) and then I have several other blogs like sub-blogs in separate directories under the same domain name (each were separately installed), but all in one database. Each blog has separate "terms" tables, where the tags are stored.
I would like my master blog to use tags from all of the different blogs installed in that database in order to create a tag cloud of all blogs. How do I make the master blog use the tags from all the different "terms" tables?
I am using WordPress 2.7 and looking for a simple solution, i.e., perhaps just typing in the separate names of the different tables somewhere.
Ideas? What would be the best and fastest way of doing this?
