It would be great if:
1- Could enter some member #'s that could be excluded. I have my Admin account and then a generic account that I use to check permissions on user groups. I don't need to see the alert when I am the one logging in.
In the config options, add a new array to store the allowed mulitple IDs:
$multi_id_allow = array(1, 2);
Then replace:
}elseif(!stristr($multiple,"c{$Uid}c") && $Uid > 0){
with:
}elseif ((!stristr($multiple,"c{$Uid}c") && $Uid > 0) && !in_array($Uid, $multi_id_allow)){
This will prevent the PM being sent if the Uids in the $multi_id_allow array share the same computer and browser.
