Oh wow, not many people make the Harvest Moon/ Rune Factory connection. Yep! It is based off the games but changed slightly so non fans of those series can enjoy it too. Haha, that's so awesome someone noticed it!
Well I'd say it varies on the day, everyone is busy so some people post less than others. I try posting at least once every day or two, but again it all depends on who's online and when.
The character list is up to date, like I said some members don't have as much time to post because they are busy but in general everyone is pretty involved.
