[mythtv-users] How to reply to messages in mythtv-users Archives?

[Sammo]

Sorry for this rather dumb question, but how do I reply to messages in 
mythtv-users Archives?

If I click on View by: [Thread] (e.g. for March 2005), then click on a 
subject heading, I can read the message. Then, if I click on the 
sender's name, the link points to 
mailto:mythtv-users%40mythtv.org?Subject=%5Bmythtv-users%5D%20Sound%20woes&In-Reply-To=1109031788.3044.14.camel%40lathe.slh.lan

This opens up a Compose message window in Thunderbird, and the subject 
field is filled in automatically. I can also copy and "Paste as 
quotation" the message I am replying to.

But the problem is that after I send my reply, it is not shown as a 
reply to the original in mythtv-users Archives! I guess it is something 
about the In-Reply-To field, so how do I get Thunderbird to use it?

Thanks heaps :)
