We want to have a specific, screen-covering popup when a new user enters our wiki, giving them a link to a page where we have guidelines set up for how to contribute to the wiki. We feel this is necessary because a lot of new users have recently started to come in and seem to be making edits while disregarding welcome messages and the like, due to either not noticing the notification or simply not caring about messages.

Is there a code or extension for this sort of thing?
