I use Isnare because of the numerous blogs my articles get posted too. I find a combination of article submission sites works well and have platinum membership in a few. I dont use submit your article .com found them not enough bang for my bucks Usually only takes a few articles for traffic and seo results to improve.
I submitted some articles to Isnare , it has been 10 days and no response from them as yet. sent them a couple of emails but no response from them as yet.
I have nothing against Isnare, i bought credits to see how it works so i can upgrade to a platinum account but getting no response for articles submitted for nearly 2 weeks though they mention 1 week is something that bothers me.
they are sometimes a bit slow but worth the wait I probaly becuase of the amount of submissions they do get. The wait is worth it as they manually check each article
