O.K. I was tooling around in the underlying database tables of my WPMultiSite MySQL Database today and noticed something odd. I "NEVER" set up my database prefix as "wp_" - I always give it a different prefix. I have several subsites set up for this MultiSite configuration and the main site and the subsites all have the same prefix that I initially set up. However, I noticed a set of tables with the "wp_" prefix and it got me to wondering. Does a WP MultiSite application also set up a set of tables with that default prefix regardless of anything that I do or is this some type of anomaly?
Thanks in advance for any information. I've not found anything to lead me to believe this is normal.
