You were not leaving, were you? All you had to do was so put a thread in Battle Staff, and a message in your sign if you really wanted other members to know your whereabouts.
That thread would not evolve into anything, as it had no real topic. I mean, people couldn't really comment 'Oh, I luved him', since you were coming back.
Anyway, what is done is done, and I really don't have to give any excuse for it one month later.
--Edit--
Anyway, since you don't really have an offline life, BF may actually start having more new posts, so welcome back.
