Hi, I am not sure if you find a PR1 article directory that easy to approve your articles then, would you think it worth to submit more and more? As you know some other directories have their own privacy and policy that caused some difficulties to submit articles. I know you can guest which directory i mentioned Could someone go and check? www.wellarticles.com Or we better tried to re-submit to the same high page rank directory again and again? Or better we do it both?
don't get into game of pr. just remember that every submission is useful, what if that dir. turned into pr5 by next update???
I second that... you never know what will happen, just submitting your articles anywhere is usually a good thing and will result in backlinks and sometimes a higher PR!
