> I submitted my website to you a few months ago.
Thanks. We always like to get good sites suggested to ODP.
> Looking at my sites visitor stats the other day, I noticed that an editor visited my site.
You can't know from your stats if an editor visited your site. It could also be one of the tools we use.
And if an editor did visit your site you can't know why he did is.
It could be a review but it could also be one of several other reasons.
> To my disapointment, my site was not added.
As there is no reason to think the site was reviewed there is also no reason to think it was listed or rejected.
> I was hoping that I might be able to get in contact with an editor & discuss how I can improve my site to get listed in the directory.
Sorry, you can't. We are not here to discuss indivual sites and how to make them listable. You can read which type of sites we will and which we won't list by reading the guidelines. Simply said: it is all about enough unique content.
> Editors, please feel free to contact me, I am open to any criticism.
Sorry, but you won't be contacted.
