A bit duff here...Could anybody please explain?

Occasionally I find links to my site on yahoo with proper title and description of my homepage, but the given link is something like:

www.mydomain.com/?N=D

Where does this "?Letter=Letter come from????

 

Funny. I noticed the same thing tonight with one of my new domains. I'd never seen it before.

 

When you have an open directory... (list of files or images, etc)

?N=D means it is sorted by name, in decending order
?N=A means it is sorted by name, in acending order.

?M=A date modified
?S=A by size


ETC.

 

Thanks for the explanation, would have puzzled me forever and a day...
