Links

Nifty building site.
Marketing metrics on the grid -learn who's visiting.

A little script to tell which prim in a link set has been touched.

default
{
    touch_start(integer num_detected)
    {
        integer link = llDetectedLinkNumber(0);
        llOwnerSay("This is link #" + (string)link);
    }
}

Word is that the new llSetLinkPrimitiveParams() has the 0.2 second time delay and will only allow work on prims using the standard constants (all, one, all-but-root, etc.) So, sadly, there'll still be a script in every prim in a lot of projects.
