Thank you very much for your response. Please allow me to clarify a couple things within your original response.

Thank you for this, this is where I actually learned the suppress command I used but this is confusing (see below).

The link above indicates that thresholding is being deprecated. I originally believed that in the future, threshold.conf would be going bye-bye so using it now would be counter productive. Before writing this response, I again re-read the filter readme and the second time I think I read it differently. The second time I read it, I understood that the standalone threshold statement would be deprecated. Is this different than using threshold.conf?

Absolutely what happened. My confusion is in the fact that the suppress statements in yesterday's snort.rules are still working today even after pulled pork downloaded and updated snort.rules. My suppress statements are still working even though they are not in snort.rules due to being overwritten by the download today. They had to be written elsewhere? No biggie other than should my suppress statements not be correct, I have no idea how to delete them.
