Your Shameless Host
Hi! Welcome to the personal blog of Jason Stirk (Griffin) - a slightly unhinged web application developer living in Lismore, NSW (yes, that's in Australia).
I run a software consulting company called Aurora Software.
I actually downloaded the 1.0PR last night and was playing with some of the schwanky features with Message Grouping. Although this feature has apparently been there since 0.9, I only found it last night and was very interested. I strongly suggest you have a play with that and the new and quite schwanky RSS aggregator support. The new default theme for Thunderbird is also looking quite nice.
Just remember Paul, you said last night you'd "Wait until the 1.0 stable" to try it!
