If you're going to be away for a few days, weeks, or even months, and you're roleplaying with people, you can set this up so it appears in your profile. It's a great way of letting people know you won't be around for a while, or even keeping people apprised as to what's happening. A Leave of Absence (abbreviated: LoA) is exceptionally useful, especially when real life gets in the way of roleplaying. The maximum length of time you can mark yourself as away for is 180 days (nearly six months), but you can extend this by coming back within that six months, putting back in 180 days, and saving it again, to refresh it.
