Scales to at least 250,000 entries

I am running this plugin with 250,000+ directory entries and 1500 categories using the cMap template and the Form extension. This was my greatest concern as the directory will eventually hold several million entries but right now there is no sign of performance degradation at all.

While front-end customization has been relatively simple, Steve has been great at responding to support requests for code snippets where needed.

The plugin comes with a lot of pre-defined functions enabling the output to be rendered in blocks and the Link and Author extensions have enabled me to integrate efficiently with the standard WordPress authoring capabilities.

The only downsides have been that the documentation is not particularly thorough, which has meant a fair amount of forum searching, and you need developer knowledge to add new fields to the Form.

Overall, however, a very impressive plugin.
