Removing outdated day limit for posts. I know why it was created, but that time passed and also community became much bigger so 20 posts per day sometimes is simply not enough for finishing even one discussion, and when you come back next day the topic is... well, already somewhere else and diggin a post from 10 pages ago looks more like necroing.
If it's impossible to remove it for any reason, at least update cap limits for 60/70/80 levels because now 50 level is last one in "upgraiding" chain.

Better tools for formatting posts would be good indeed. Some design update is welcomed as well, though it's not bad now too.
