If nobody is replying to your posts, again, be patient. It takes much longer for posts to reach some sites than it does others. It may take six days to travel around the world, and then six to get a reply. Besides, people will respond if they feel like responding to it. Some people won't respond because they think someone who knows the character or issue better will answer, or they just aren't into a particular title or team.
Newsreaders are really funny things sometimes.
Some won't show your articles until you exit the newsreader and restart it. Others might have a delay of a few minutes until your post appears. If you aren't sure how your newsreader works, ask in the group news.newusers.questions . Through this service, you can read as many posts as you wish from any newsgroup or author, and you can post directly to the group or send email to the original poster.
