VaultWiki and altering of POST table
As you may imagine, any messing with the POST table is a huge pain for the big forums, so I winced when I saw VaultWiki adding a new column to it in 3.0.0 RC2.
I see that the new field is used to indicate the usage of Wiki BB code in a post. I'd imagine the rate of Wiki/standard BB code usage will be very low, so why not use a separate table (which will be very small) for that flag and JOIN it when needed?
