Squeak-dev digest, Vol 1 #926 - 37 msgswebmaster pagancities at pagancities.comThu Nov 7 09:08:59 UTC 2002
FYI... alphaworld is alive and well.. unless one talks finance. I know.. I own a world there. Many people from AlphaWorld.. (now known as ActiveWorlds) are now looking at Croquet. It isn't what we are used to.. but being an experienced 3D end user group we can certainly see the potential of Croquet. Well done! Thank you for allowing us all to be involved. This is the first time I haven't been technically intimidated to post in this group. I think Croquet has a place for us all. Malka VR Village.
