So, I was thinking that it would make sense if we had links on all pages....

e.g.
If we had
Category: Doctors (no links)
Subcategory: Ophthalmologists (200 links)
Subcategory: Gynecologists (500 links)

Then, in the current format, when from home, I click on Doctors Category, it shows me the 2 subcategories - Ophthalmologists and Gynecologists, and that's it. When I click on Gynecologists, I get to see 500 links....

My suggestion is that when I am on Doctors category page, in addition to the subcategories,
instead of saying "There's no web links here.",
IndexU should show 700 links there...i.e. all links of all subcategories. (of course not all 700 would be shown on the same page...use pagination as normal)

This way, user theoretically starts with the whole link database, and each successive click into a category/subcategory would "fine tune" the results...making them more and more relevant...

This is probably easy to do in the template...I just don't know how....
