Is it possible to edit the date that a user last logged in?  

I want to prune our member list, with some users having not logged in for over 10 years. However, there are a couple of users in that list that I need to retain their accounts so can I edit their last logged in date, so not to delete their accounts when I prune?

Thanks.

There is no way in which you would be able to edit the last logged in date, without manual database manipulation

As a workaround, you can temporarily move those users to a different group and avoid searching inside it for users to delete. Once you're done move them back to their original group.

Thank you both, that workaround should do what I want to achieve, thank you.
