How to post to GCC lists?

[Omar Torres]

Dear All,
  I recently started working in a GCC backend, and as a result I expect
to be actively participating in the ML.
   That said, I have questions on how to properly and efficiently do a
post. I want to remove the annoyances that at the end just unnecessary
waste everyone's time.

1- I noticed that when I reply to posts, the "References" are not
preserved, which leads to messages in the same threat not to be linked
together. I am using Thunderbird as my email client. When I go to
View>Headers>All the References field looks accurate. Is there a trick
to make this work? Should I use instead a different email client better
suit for GCC ML?

2- Currently, (1) is the only thing I have run cross. I am sure there
are other issues that those of you with more experience have already
discovered and solve. Any other Dos/Don'ts or tips/tricks when posting
to GCC ML?

Thanks,
-Omar
