Lyrics, Tab, Titles - simple questions

[se.e]

Hi all!
I'm a new Lilypond user and I've some very simple questions for you.

1) Titles -- I have:
tagline= "copyright©2004"

Why in the .pdf '©' is only a 'c' (there's no circle)? This don't works with
'®' too.

2) Tablature --
if I've a chord (ex. {<<d a d'>>} ), in the .pdf there is a line cross the
numbers, why? And...is it possible to choose line-up or line-down (from the
number)?

3) Lyrics -- in the manual (page 24) there are tips for melody, lyrics and
chords. I've made something like this:

\score { \notes {
 <<
{ \time 4/4 \clef violin \key g \major
 s2. d'8 d'8
 d'2 d'4 e'8 g'8
 g'2. }
 \lyricsto "" \new Lyrics \lyrics
 { Oh the  win __ter }
 \new ChordNames
 \chords { s2. d4 g1 }
 >>

But now I've the lyrics (with the chords) above (not below) the melody,
where I'm wrong?

4) Posting here -- for a new thread I've just to send an e-mail to
address@hidden but, to reply to an opened thread what can I do (on the
web page there is just 'reply via e-mail to ...')? (I can't find something
like 'reply to the list')

Thanks in advance for reading and sorry for the number of questions!
Cheers.
