I would likely be more active in this forum, myself, but the forum style is confusing to me. I can't just reply to the thread, for instance, I end up replying directly to the post above mine -- and that can cause much bad juju, because that makes it look like I'm making a personal and directed attack on that person if I have something to say that isn't so good.
PHP style is more to my liking. I really also would like to be at least given a heads up every week or so that "Hay, we're working on this, haven't forgotten you guys!" It's really creepy when the moderators/owners are this quiet. I'm used to seeing a lot more presence. Not necessarily interaction, which is nice, but presence.
