Hello, Suppose I didn't subscribe gcc mail list, and I want to share my comments for an existing mail thread after I read it in the mail list webpage, what should I do to make sure my reply can be linked into this thread? It seems that composing a mail with subject like "Re: ORIGINAL-SUBJECT" and then sending it to mail list doesn't work. My email at http://gcc.gnu.org/ml/gcc-patches/2012-03/msg01763.html doesn't get linked to expected mail thread at http://gcc.gnu.org/ml/gcc-patches/2012-03/msg00461.html. Please advise, thanks in advance. BR, Terry
