I have been submitting articles and poems left and right for two weeks. Duotrope has made my life so much easier. If you are not familiar with Duotrope, I would suggest everyone try it. This is a way to keep up with all your submissions in one easy place. It will give you the name of the publisher you submitted to, the name of the piece you submitted, when it was submitted and if it was accepted or not.
I may be way behind everyone else, because you may already know about this wonderful tool, but it has helped me triple the number of submissions I send out. Now, it's the waiting for a reply that is getting to me!
