Sorry & Stupid Question

[Dorothy over the RGB]

Hi,

Sorry for the little HTML pollution, I used WinXP/OE instead of my Mac for my 
previous post. Stupid Question: the digest messages says "When replying, 
please edit your Subject line so it is more specific than "Re: Contents of 
yellowdog-general digest..." However, while setting the subject line to 
"<specific_subject>" or "Re: <specific_subject>", my post creates a new 
thread. Do I have to switch to non-digest subscription?
