I have an idea. What if we all state right now the things (not counting spontaneous life events) that could take much of our time and possibly cause a sudden temporary hiatus on the RP. This would help give us an idea on why someone is gone whenever they do get into a sudden hiatus and thus not make us immediately jump to conclusions (well at least, for me, because I tend to overthink a lot).
I guess for me, the current biggest responsibility is college, so...I guess that doesn't need much explaining. =)
