1. This is my summary line format:

    (setq gnus-summary-line-format
          "%U%R%z%I%(%[%4L: %-23,23f%]%) %s{%B}\n")

'%f' will replace 'From' with 'To' or 'Newsgroup' in summary list.

2. This is my ignored from addressses:

    (setq gnus-ignored-from-addresses user-full-name)

3. I use Non-english newsgroups. So my personal articles is
gibberish (by '%f' above) in Summary line or in local archive
folder.
