I think the first issue took about two years, and then they were running okay, and recently it seems things have slowed down, perhaps because in those two years, they may have been accumulating material that comprised much of the first three issues.
The 4th issue is a travel issue; there isn't supposed to be any carry over from the other issues. I haven't heard much from her either. However, I don't think Dave Parker is doing the press checks anymore, so that could affect the schedule. I do wish her the best however.
