I honestly think they're helpful if someone is going to leave for a long period of time or going away for good. And with intros, good for longer periods of time. Should take my own advice heh
ooooh~
Interesting!
I personally haven't really ever made these types of threads, because I never typically know when I'm going to be going on a hiatus/leaving or returning or whatever. It's usually kind of impulsive with me, & I kind of do what Torskite said & leave a note somewhere else, like on deviantart. The majority of the community probably wouldn't be too interested in the fact that I'm going on vacation or whatever, so I usually only tell closer friends that would be affected & wonder where I am.
