What are some good retention tips?

[JoesHO]

as was mentioned before, many of the sites today just do not even try to retain , or so it would seem.

Please share with me some tips that the old school used to retain ( not the auto rebill of course LOL)

But seriously do things like this work?

1.) exclusive content?
2.) multiple upsells and interactive devices such as games or message boards
3.) lower price for remaining a member ?
4.) pre pay 90 day memberships?
5.) added sites included as a one price for all type of thing ,etc.. ?

anything that comes to mind please share your thoughts on .
