Many websites uses subscribtion system, make people remember logging in everyday.

How about reply via email and mailing list mode?

@xiasummer

Many websites use bonus system, like user level (which often has 10 even 100 levels, rather than 4 levels in Discourse) or Forum Coin , to make people feel that they has gain sth, to make them feel the stimulation / motivation.

Trust levels are more about enabling things based on trust than about showing off. But how about the badge system? Totally awesome.
