Thank you for sharing Reynold! The link is indeed the Speckle@Arup Installer, which comes with a few extra things and is intended for internal use in Arup, but of course others are free to use it as well.
The soft release of the stand alone installer for the GSA connector can be found here (look for the latest gsa Pre-release): Release gsa/1.0.3.57126 · arup-group/speckle-sharp · GitHub
And thank you for helping Lance to get started. I’ve added Lance to the Arup internal Speckle user group
