I have two websites / webspaces. One has five installs of WP and the size of the database is 4MB. This is fine because this site has 100MB of space and I am only hitting 65%.
The other has one install of WP and the database is 4.43MB. As I only have 10MB in total for this site, size does matter.
Is there anyway that I can "optimise" the database or can I cull some stuff to give myself a bit of breathing space?
