Hi,
My blog is 4 years old and quite naturally there are a handful of unwanted tables and fields in the database. The extra tables primarily come from BP which i had installed only for testing. Extra fields within tables come from plugins such as 'subscribe to posts', etc (just naming a few, not blaming!).
So i wish to get rid of all extra tables and fields within my DB, keeping only the core along with page/post data within.
Basically, i wish my database was clean/sanitised.
Any ideas?
is this the schema? - http://codex.wordpress.org/File:WP3.8-ERD.png
PS: my knowledge is quite limited w.r.t. mysql.
