If you are able to run on a shared account, then it is for sure not a Big Board as intended for this forum.
This forum was created so admins of Big Boards can discuss topics that come with running a board larger then the average. Thinks you can think of are: Multi server setups, specialised search routines (Sphinx), etc..
Everything that goes beyond what a 'normal sized' board would need to do in order to make their site work.
