Thanks. I'm really not an authorized contributor yet. What is the way
of sending you questionnaire and ICLA? Should I print them, fill by
hand and send by post office? Or scan them and send by e-mail? Or
there is a way to submit them over the internet?  I have search over
the ASF site, but found no hints on this point.
