I've just started trying www dot tradeweblinks dot com. Too soon to tell how effective they are. Process includes uploading a .php file (very easy, just copy & paste code to a notepad file & save it as filename.php). I was wondering if a .php page will get as good a PR as an old fashioned .html file - any ideas on this anyone?
You can submit to as many directories a day as you won't and it will not hurt you. Most directories take days even weeks or months to approve links.
