There is always a delay from when I submit an article to this publication to when it actually gets published. So, on time sensitive posts like calls for submissions, you are going to miss the earliest calls. My suggestion is to go to my blog (Publishing … and Other Forms of Insanity), and check out the tab marked “Calls for Submissions.” http://publishedtodeath.blogspot.com/p/calls-for-submissions.html
That is where I post calls as I collect them. So, if you go there periodically, you will get a jump on calls early in the month. Also, if you simply check my blog toward the end of the month, you will see my Calls post for the following month.
