I'm seeing a drop in renewals and wondering: Have you, do you, or don't you bother to email members that don't renew?

If so, do you ask why they didn't renew and invite them to email you back, or do you have any sort of anonymous poll page online where they can check off some items and a comment box?

Do you offer a discount to come back to the site? If so .... Is this proving profitable? And is that set up with a link to a special signup page that gives them access for whatever offer you made to them?

If you did email ex-members at one time, then stopped, why did you stop?

Would appreciate any other feedback on membership retention that any of you care to share.
