I am starting to get a feel for the scripting language used in Hal's brain and plugins.
I have found a Wiki at this address:
http://ultrahalscript.pbwiki.com/Is this the official Hal script wiki?
Is the wiki still being maintained, or has it been abandoned?
I did not get a reply when I filled out the request for access to the wiki.
There is not a complete help site for scripting, so I am volunteering to help getting one completed.
Let me know if you are interested. I still have quite a way to go before I really understand the language, but I would like to contribute, if you are interested.
