How many names can TNG support?
Theoretically, there is no limit to the number of names it can support. I have 14,000 names in my database and have never had a performance issue. Some have many more (I know of one user with about 1,250,000 names). If your database is that huge, however (a few hundred thousand names or more), you may begin to notice a slight performance drain (pages will take a few seconds longer to display). The vast majority of people will not experience any problems, since most files consist of 10,000 names or less.
