This spot is designated as a place for users to post if they are going away for a while; either moving, vacation or any leave in general, and also a notification of your return as well.
This helps me know if you've had a reason as to why you haven't posted. I don't want to constantly send you messages if there is a reason for your absence.
I do ask that you post something more than just a "Leaving" in your message. You, by no means, have to tell us in detail why you are leaving, but maybe something like; "Leaving - vacation to France", "I'll be gone for a while - Moving". If you don't feel comfortable telling us, don't...just don't post a plain "Leaving.", that is all I ask.
A timeline for your return is not needed. Who knows you might get tackled by a man in a banana suit while buying a double shot mocha light cream twice roasted bean espresso, and might need to be gone for a few extra days. xD
Granted, that probably won't happen...I very well could.
