PSA, apropos of nothing at all: moderators can't merge user accounts; that has to be done by SE staff. All we can do is point them to the help center and explain why it's a good idea.
I use a comment like this:
> Hi! You have a couple of user accounts. If you’d like to merge them (which will allow you to [edit](/help/privileges/create-posts), [comment on](/help/privileges/comment) any of your posts and [accept an answer](/help/someone-answers) on your question), please see the [instructions](/help/merging-accounts). Welcome to the site!
