Webmaster tools with Google, Yahoo and Bing
 

I am presently making use of Google web designer devices. I sent my sitemap using their device, etc . I am mindful of the reality that Yahoo and Bing supply theit very own webmaster tools area. Can I make use of all 3 websites' devices or should I select one of them and stick with it? Do not know if there is any kind of penalty for using numerous tools?

no penalty will happen you can use of it....
