Right now it seems that users can submit anything as an URL, e.g. http://asfwasrwee. How can I make sure/auto-check that only valid URLs are submitted? Thanks!

You can't. You can check reciprocal link urls for your link although it's dangerous to do so and can lead to tbe browser hanging doing nothing when the page doesn't exist, but not regular site urls. To do so would simply make attempted submissions take forever, or best case scenario would lead to URLs being rejected because they happen to be slow loading.

Actually I didn't mean checking if the site exists - just basic validation if it's valid URL syntax in the first place. Really nothing fancy, as far as I'm concerned it needn't even check for specific TLDs, but every URL should at least have a . and some kind of extension.:)
