I'm just wondering, how did this come about?
It might be handy for some people to be able to post more in advance, and not have to worry if they one day got hit by a bus and ended up in the hospital, without internet access, for a while.
Most people don't go away for more than 60 days, though stranger things have happened. So what is the real reason why there's the limit?
The point is to keep people active. It's to avoid that some people would post a lot of posts and then stop posting for like half a year until their points are low again. Also, it would encourage more copy-pasting and other non-desirable ways to get a lot of points quickly.
Although it is off-topic, what about locking users account when one's points reaches 0. Sometime some user's point go extremely below like -200. When they restart posting, their hosting account get deleted because some moderators find their points too low. I know points are reset to 0 on request in those cases, but will it not better if points never go below 0. There may be some mechanism to automatically lock user's hosting account when it reaches 0. Moderators can send 1 or 2 warnings after it. When the user do not respond, delete his hosting account. When the user decides to come back, he can restart posting and request new hosting account.
I don't think it matters that much. As has already been explained, the point is to keep users active. And even if you are going to be away for more than 60 days, all of the moderators here seem to be pretty cool. I'm sure that if I said, "Hey, I'm joining the U.S. Marines and I'm going to be away in boot camps with no computers for the next 13 weeks" then exceptions would be made - especially considering I have almost 2000 posts and have been a very active member since 2006. Frihost thrives off of its active members that make solid contributions to many topics. Therefore, I really don't see them giving an active and good poster problems because an extended leave.
Besides, these occasions are usually few and far between. Most of the time we have at least some (even if limited) access to computers and all it really takes is two posts a week to stay positive. For instance, this post is probably long enough to be worth five points. So if I post this and then come back in half a week and post something even half this length, then I'm good for an entire week and I haven't even had to try very hard! It really only takes 10 to 15 minutes combined per week to stay positive. Most people post far more than required simply because they want the community to stay active because that is more fun for everyone. It's only the occasional exception - like someone joining the service (and I'm only using this example because I just got back from my friend's going away party; he's going off to the Marine bootcamp where he will literally have no computer access for the next 90 days or so) and as I said, I'm sure the moderators here would be cool about that if the member has proven that they are indeed an active and solid contributor...
