Reward Ideas

First of all Id like to say I have only been a member for a short time so please forgive me if anything I say has already been said/done. I know that if its a players birthday they are rewarded with bonus points and I wondered if it would be possible to also reward them with bonus points on the anniversary of their "joining day"
Idea 2 Rewarding players if they sign in and play for certain amounts of time ie if they sign in and play every day for a period of 1 week," weeks or 1 month... I think a small reward of some kind of badge to show their loyalty would be nice. Another thing along the same lines would be a special badge showing "player of the month" rewarded to player that has spent the most amount of time playing throughout the month. Only one person at a time may have this badge then it will be passed on the next month.
Idea 3 I notice that many people only play the "big Jackpot Games" then disappear so it would be nice if once or twice a week a random bonus game could be played to reward those that play for longer periods as they have more chance of catching them if online longer.I would like this especially as I like to spend as much time playing but am unable to play at night therefore missing bigger games.
