What are the legal guidelines for using scala logo?


as far as i know, the scala logo and the scala trademark belong to epfl… i am having difficulties to find the exact guidelines (legal guidelines) for using the scala logo.

according to https://groups.google.com/forum/#!topic/scala-user/bCC-R0FQn1w it seems that it is allowed to use scala on material related to delivering scala course in organizations.

can i use the scala logo (together with other logos of other technologies) in a rollap / banner describing my company professional training services to organizations… ?

thanks in advance,
