SO glad I found this thread and I'm not the only one in this bizarre limbo!
No, Susan, you're not the only one waiting to hear on a 2013 submission. They've had one of my manuscripts since then, and it only turned into "under consideration" after several months. That was *after* they closed an entire submission period in order to to catch up.
The most unprofessional part of this is that they still claim, on their submissions page, that they'll respond within 3-6 months. Given that this clearly hasn't been true for quite a long time, and they refuse to answer any emails about status, it would be nice of them to accept that they're not anywhere close to hitting their announced targets and give everyone accurate information so we can make more informed decisions.
