No idea if it's worth the effort of installing it. I got disgusted with it and decided to look elsewhere. 4 Canada iLink is one of the best directory scripts I've used so far and a real cut above most in the freeware market. It even comes with a helpful support forum. When it works, it's great.
Documentation is vast and spread out all over.
Others have little problems as it self installs. Support is great through forums. Very large and time consuming to put together. Files missing like graphics, html, will make you crazy. Very difficult to install on my non-standard account.
