Actually there was one who used to post here, and he went to Yeshiva shel Maalo World, last year.
But I wouldn’t think anything you post here would have any effect in one’s after-life. Actually I think it would be an excellent opportunity at gemilas chesed, to write chizuk, comforting words of encouragement and support to those still with the living. It’s those who could use the powerful, uplifting gift of the kind, sympathetic word.
