Chris C., what mailing list was this conversation orginally sent to?
Looks like all your headers were clipped (as they always are!). This
was sent two days ago but I'm only now seeing it only because Dave
forwarded it to the proper lists..?
Anyway, we need to talk!

>>>SqueakMap uses Monticello to load packages
No, it doesn't. SqueakMap knows nothing about Monticello. SM uses
plain Smalltalk .st scripts. That's where its flexibility and power
comes from. Currently, many, but not all, of those .st scripts invoke
Monticello loads because that's our current SCM tool.

Well, that certainly defeats the whole purpose of a Catalog. I
certainly won't be using the "new" one if this is your intent.
Chris C., please DO NOT rip down any more existing Squeak services.
You need to coordinate such drastic resource changes with the

Chris C., clearly you have not thought this through..

Chris Cunnington, I suggest you take this attitude and your work over
to chriscunnington.com, where you are free to create a new empty
SqueakMap and invite people to use it. If you can get community
excited and using it, then the transition will take care of itself.
I repeat, Chris, do NOT do to SqueakMap what you did to the old
squeak.org website. You MUST involve the community and win their
