I'm not pointing anyone out specifically but I've seen a lot of "I hate the 5 post requirement" or "I don't think it works" posts in this thread, which is completely counter to
a) the spirit of the OP, and;
b) the actual request of the OP.
Obviously people have complained/had issues with the five posts/four hour requirement, otherwise this thread wouldn't be here...nobody is saying anything new and frankly, not helping the conversation. This isn't a petition drive people so "me too" hold exactly zero water and in many cases proves the rule.
Think of the mods as management. At work, do you go to your Supervisor or Manager and say "This sucks, change it!"? Not more than once you don't. Any manager worth their salt wants you to come to them with your problems, obviously, but they appreciate it when you come to them with ideas on how to
fix what's broken instead of just complaining. Is four hours of active browsing the forums too long? If so, articulate why you think so and not just "because it's hard/boring". I'm not saying it isn't hard or boring but I'm saying come up with a cogent, reasonable argument for why the time should be shortened.
I had a couple of questions that I really wanted to ask before I joined the forum and I'd been reading it for several months before I created an account. While I was waiting, I was just chomping at the bit to ask and, in some cases, reply to threads that I was just
sure I had to reply to (I'm an incurable wise-ass). Turns out that all three of my vital questions that I just couldn't wait to ask had already been answered...multiple times, one of which in the newbie forum.

Not saying people haven't searched already because search can be difficult to get the terms right, but it's amazing how much ground has already been trod.
If you have a suggestion, that's what the OP is asking for. If you're just going to mitch and bone to raise your post count...take 10 seconds in another thread and at least try to be constructive.
