Dear all,

I am using the letter module that came with context.   A sample of a basic letter is below; I have put in "dummy" for the logo and the signature, but these are working fine when I include the files. 

I have several questions:
  1. to center the footer.  
  2. to lower the  footer (closer to the bottom of the page)
  3. to delete the word "Date" above the date.
  4. to put the date above the recipient address (and how in general do I adjust the vertical space here).
  5. to left-justify the date.
  6. to control the foldmarks (for US-letter-size paper, omit, etc.)
I have consulted http://wiki.contextgarden.net/Letter but there are many things I don't understand.   What is the meaning  of "alternative=example"; what is the option "preset="  in \setuplayer[foot] ?

Also is there a better way to manage color?  I \definecolor, \startcolor, \stopcolor, but maybe there is a better way to indicate that certain sections of the letter should be in a color.  Thanks.

Thank you very much for your guidance.

Yours,
Michael
