[yt-users] yt-users Digest, Vol 67, Issue 18

[Seyit Hocuk]

Hi Matt,

Sorry, I'm new to the mailing list and I didn't notice your email 
before. I was set on Digest mode, which I find quite chaotic. I now 
switched to regular mode.
Thank you for your reply. I already found a workaround actually, but 
it's ugly. I will try your suggestion the next time I need it. Thanks 
for the swift reply.

Kind regards,
Seyit
