Hi, I've searched the forums and I can't see that anyone's discussed this before.
I'm currently building a site with Mambo and there are a couple of cool modules for sending email through the site. E.g. someone signs into their Mambo site and a little (4) appears next to their inbox telling them they've got mail. Some modules implement things like Squirrelmail or Hoarde for this.
My question is, does anyone think this would be possible with WordPress and if so how? (And, please, we don't need to get into arguments over whether or not WordPress should be forced to act like a CMS! I'm sure we're all sick of that one.)
Just strikes me as a great feature, especially if anyone's using WordPress to design sites for others.
