In the version of ActiveState I am running on my win box, that doesn't work. I use the new PPM version 3, in which they may have changed the commands? Anyways, to add more repositories, the command is (now):

rep add DevelopHelp http://ppd.develop-help.com/ppd/
[download]

And there is no need to call any save command.

UPDATE: I realized I maybe should add how to search the different repositories: Type

rep
[download]

to get a list of the repositories you have listed, the active one will be marked with a leading '*'. Then type

rep set X
[download]

where X is the number of the repository you want to search.

help rep
[download]

will give you more commands.

Otherwise, a very good post, and thanks for the extensive list of URLs!
