I am trying to write a plugin that modifies the dashboard for most users.
I will be the only administrator of a website; I don't want other users (neither editors) to see the wordpress-related infos; I'd rather show them my advices on posting, editing practices, etc. So, the thing is, I must prevent wp from showing the actual content of the dashboard and substitute it with my content. Which hook should I use? A small example (just a couple of lines) would be very helpful.
Thanks in advance,
