I've walked away from these boards for months at a time when my studies and real life were overwhelming me, and without a single comment on my absence except on the private ENPublishing boards where my business partner (Russ) and one of our production managers (Ryan) would bitch about my disappearance.
So, yeah, no one in the general public of the baords noticed my absence. Which isn't that surprising considering my lowly post-count and the fact that we are all used to operating in an environment where people come and people go. Our only snese of continuity is that we see the same names in the posts, week after week. As long as some of those names are still there, we are unlikely to notice the absence of others. That's the nature of the human mind, we notice coincidence, but are oblivious to lack thereof.
