Free Web Submission gives you the chance to submit your site(s) to a large number of Search Engines with a single click.

Before you do this however, make sure that all your meta tags are properly laid out as some sites will reject your submission if they are not correct.

Also remember not to over-submit, about once a month is probably the ideal.

It also has an excellent popularity checker, similar to Widexl, but possibly more accurate as it seems to check a bit deeper.

In addition it also has an excellent site ranking tool which allows you to check your ranking with a number of leading Search Engines for a particular keyword or phrase.
