I'm having a small problem. Well, the real problem is that I'm not as familiar with PHP as I need to be.

I want to allow the URLs to be shown when someone comments on my blog (www.seo-factor.com), but when one leaves their URL, it places mine in front of it on there link. For example:

If user puts in their comment, and puts their homepage as www.visitorspage.com, once they post the comment, the link becomes http://www.seo-factor.com/http://www.visitorspage.com. This is disheartening as I run an SEO blog and would love to let these links on my site. I don't mind the work it takes to clean the spammers that flock to these.

Any help is greatly appreciated.
