Yes, but the issue become, where/how to store it, then if the site needs email verification to validate the user. Then the issue comes in with mods, that redirect users to certain places, or forces them to read a post or pm before continuing doing anything.

Just way to many variables and hurdles to try and overcome to get them back to the post.

Look at it this way, as vBulletin stock setup, if I am reading a post as a guest, then decide to reply to it, I need to register. Once I do I need to find that post again. I am sure if there was a easy way to do it, it would be in the core software already.
