The EUROCALL/CALICO Virtual Worlds SIG Ning, managed by Graham Davies (Groovy Winkler)  and Randall Sadler (Randall Renoir). The Ning includes a blogs section to which any member of the Ning can contribute.

Graham Davies (Groovy Winkler) has written a substantial section on SL at the ICT4LT website, Section 14.2.1 of Module 1.5. It contains numerous links to other sites, resources and videos and also a link to Graham Davies's Introduction to SL Viewer 2, which is a set of downloadable training materials for newbies in Word doc format. This is not a blog; it is part of a permanent website, but it is regularly revised. The introductory training materials take beginners step-by-step through the basics and contain links to many other resources on the Web and inworld. The ICT4LT blog is associated with the ICT4LT website and contains occasional postings on SL, for example on the 1920s Berlin Project and Groovy's SL videos (relating to the old EUROCALL HQ in SL).
