Classifieds: generate pretty URLs

Hi, I'd like to have 'pretty' urls from the Classifieds, IE, "example.com/classifieds/?ad=4" would be "example.com/classifieds/?ad=san-francisco-training-center" - BEST would be "example.com/classifieds/san-francisco-training-center" without the query.

Assuming I'm not very smart about PHP (and I'm not :slight_smile: ), can you give me a snippet to make this happen?

(I'll bet my 'best' preference involves htaccess...)

thanks,

Charlie
