rycrostud, it's not that long ago that you submitted, so it will probably take a while longer. The .php issue will be covered in this thread [webmasterworld.com] in the Website Technology Issues forum.
It would probably be a good idea to arrange for a couple of good inbound links from sites that are already indexed, which can be more effective than actually submitting. Also, if you haven't already, submitting to Open Directory Project [dmoz.org] is a must.
Thanks for the advice. I posted the same question on the thread you suggested - I think that thread's been inactive for some time. Perhaps I'll start a new one.
I've also posted the question on an alternative forum site - they are advising me to create an html page, containing meta tags & descriptive text in a hidden layer and redirect to my php home page. Don't really want to do that though cos it might be considered spam.
