Because the databases are text files and located on the same server, would there be a speed problem having more than 20 databases.
For example people that have already paid for advertising should come up first. I have people that have paid for different levels of ads.
So I know I need at least 3 custom databases of my existing directory. The smaller databases may have only 10 to 30 entries.
Where the larger one will have about 1,900.
