It makes two big differences:

1) the subject is misleading if not suited to the contents, but worse is:

2) mailing lists are threaded, which means that if you start a new thread 
by replying to a posting in an existing thread, even if you change the 
subject. This is what you have done this time - the thread ID is one of 
the many header lines in mailing list messages, and cannot (easily) be 
changed by the user.

See:

http://news.gmane.org/gmane.comp.lang.r.geo

for a threaded view - this exchange is still threaded with the original 
posting. Thread discipline is crucial for the value of the archives to 
others - questions are _NOT_ only single exchanges, but are accummulated 
knowledge that others can search and use.

Please start a completely new message, and maybe we can resolve your real 
question.
