Just wanted to get some opinions...

My index page will be changing from .html to .php do I have to resubmit to search engines/directories manually or will it just be picked up thru the revisit?

Hope this isn't a stupid question!

Thanks

I would think they should be picked up thru the revisit, but I would re-submit anyway at least to Google or Yahoo.
If you are in the top 20 on Google/or other I would wait and see.

I know there has been some problems with some MySQL/PHP driven sites not being crawled correctly but I have had that problem.
