Hi, everyone.
Sorry if this is a wrong place to ask. I would like to complete a course on asterisk. Particularly I’m interested at:

Asterisk Beach Camp
Dates: September 25 - 29, 2006
Location: Malaga, Spain Europe

I wrote an email to express@digium.com with a request for more informatiom but haven’t got a response. Where should I ask for information about this course and for other courses in general?
Thanks in advance
