I was thinking the same thing the other day and was going to revive this thread, but you beat me to it ?

Do we have any moderators in the RM forum to move this to a sticky???

[bambambennett]

This needs to be bumped up top again. Someone please make this a sticky as it would be very helpful to those who need it.

I can setup a SL6 Linux server, Apache with mysql database and put all of the data into it.

I think this would be a better approach and cleaner.
