I've modified the usual NP_NotifyMe plugin to be a bit better :-)

First, I've included  MULTIPLE BLOGS!. All you people who've wanted multiple  blogs, here you go :-) I've tested it across 2 blogs with 2 users - should work well with more.

Also, i've modified the mailer to work with the regular PHP mail() function, instead of the NOTIFICATION

E-mails are also formatted in HTML, instead of plain text. I've removed the \r from the headers that some anti-virus programs target on.

Besides that, the options and stuff are all the same. It's still not v1.0 but it's close.

To be added: Theme support, more dynamic labeling options, anything else people suggest! Let me know how it works.

Link to plugin: … Better.php

Here's the code:



// Modded by Adeas to allow multiple blogs & better e-mails

class NP_NotifyMe extends NucleusPlugin {
    function getMinNucleusVersion() {return 155;}
    function getName() {return 'Notify Subscribers';}
    function getAuthor() {return '-=Xiffy=- (Appie Verschoor) - Modded by Adeas';}
    function getURL() {return '';}
    function getVersion() {return '0.9.1';}

    function install() {
        // create the table to hold the addresses ...    //Adeas:

                                                        //The blogID is the blog # of the blog the person wishes to
