I’m pretty sure it’s never case sensitive. When an alert goes out, we all receive it in our inboxes, ie. our name at binkybunny dot com. Whoever is on at that time, or soon thereafter, will read it first when they check their emails. You may get a response from a different forum leader even if it says K&K in your text, but depending on the message they may wait if it’s intended for one of us in particular. Sometimes a delay will mean no one has been on line at that moment (though BB usually stops by much more frequently to check for alerts). Also, if the subject is being discussed first before responding in order to know what response to give.
If there’s a server issue, like during a major holiday, that can delay alerts and posts too. I do know that if you write RabbitPam or rabbitpam, it will get to me either way. Individual emails to the BB address can be private. Alerts are not.
