So, have played around with Inviz's wpmu mailer plugin to make it work (thanks to quenting's corrections), 'de-cynicalise' it (by removing all mentions of spam and replacing them with 'email') and getting rid of the 'tags' (cos they never worked).
But... when I upload it to mu-plugins it stuffs up teh write pages - making the 'Add categories' box be replaced by a big white block and all the options maximised... take it out and everything works again.
I'm guessing this has something to do with javascript (of which I know even less that php - which is extra scary).
Am I right? Is there an easy way to fix it? Many thanx! James
