What does pid and sid in the URL stand for?
You guessed it right:
- pid = Guide ID
- sid = Page ID
I asked Slaven about this and he let me know the history: When he was developing the original "proof of concept" for the system, guides were called "portals" and pages within the guides were called "subjects"...and the abbreviations stuck.
So, originally pid was "PortalID" and sid was "SubjectID".
Now we know. :)
