Update: replying to an email instead of logging into yahoo group website worked.

I can see someone on step one list is having the same issue I was having with formatting not showing up

: Thanks Kathleen!

: Unfortunately my problem is not
: getting to or using the return
: button, it's that the yahoo groups
: web site is not reading the line
: breaks. It's as if the yahoo
: groups web site doesn't read that
: character from my phone.

: I seem to be able to insert line
: breaks here on the forum from my
: phone. Something must be different
: with yahoo groups.

: I also don't have this problem when I
: send yahoo emails from my phone. I
: can try posting via email instead
: of signing in to the yahoo groups
: website. Maybe that will work.

: I will ask on yahoo. If all else
: fails I will refrain from longer
: posts via phone.

: take care,
