What do you mean by "submitting groups"? What do you mean by "if hitting were good"? If you are talking about Yahoo Groups, they will not help you at all for the reason stated. If you are talking about Google groups, those are also useless for SEO because all the links on the countain the rel="nofollow" attribute. These groups have 0 impact on your rankings.
