RE: Not to sound morbid but...
Financial concerns can keep a person off the forums for a while too. Taking a break from the hobby or at least the internet due to a lack of funds is probably all too common. I once had several hendred posts but they went bye-bye as this place has gone through its various changes and upgrades. I personally have gone through several periods of not having easy internet access, and this is always the first place I come back to when I get the chance.
