I think the reason why we keep getting email alerts but there is no new chapter is because you changed something in the last chapter. I noticed that you edited one sentence. Even though it is just one tiny thing the site for some reason sends out an email alert. I've noticed that happens with other fics as well so it is not your fault.

- My apologies to everyone that got an update alert. I had a grammatical error pointed out and I corrected it without realizing that doing so would sent out update alerts. Won't be doing that anymore. Sorry for the inconvenience. I'll be repeating this to everyone who asked about the update, because I don't know if these responses are emailed or not...
