<Clarke> Do we have a volunteer for scribe?

Have not read the guidelines but can give a try

<Clarke> Thanks, Juhani - Kaz (the expert) is on the line and can help, right Kaz?

<Clarke> Kaz, can you match up the phone numbers? I'm not sure how to do that, and I don't think Juhani is either

<Clarke> OK

No idea how to match with phone numbers

<Clarke> So Juhani, the basic thing is to identify the speaker followed by a colon, then take write the notes. An elipsis (...) identifies the comment with the same speaker. Any other tips, Kaz?

<kaz> [ that's fine, Clarke ]
