I've finally had enough with the unreliable service provided by hotkey.net.au and am changing over to TELSTRA's Bigpond which has far more features with a far greater data allowance at an even lower price.
My new email address is riverbendnelligen[AT]mail.com.
The change-over will occur sometime late next week and I may be off the air for a day (or two, or three), so don't fret: I haven't met my Maker yet, just a better Internet Service Provider.
