Ok - admin approval is done now, too... I had a links directory hack of my own which was almost done, but buggy - so I've managed to salvage some code to expand this hack
I'll only make these mods public if the creator of this hack approves, though...
What they do:
Search -- self explanatory
Hit counter -- when a user clicks a link, they go via a redirect page which increases a hit counter in the links db, and as such displays the new total in the linkbit
Validation -- when a user submits a link, it is not displayed until the admin moderates it. admin can moderate link title, url, description, and even delete the link if he wishes.
Sound good?
