I don't think anyone is deliberately ignoring you. Keep in mind that you've only posted one story/chapter so far, and it was only yesterday. Sometimes it just takes time to gain interest and feedback. As well, you haven't yet commented on anyone else's stories. That isn't meant as an accusation or anything (as I haven't been very active in the fanfic section myself, although I would like to be), but all the same, if you're looking for story feedback, then I'm sure you'll get it in return if you're willing to give other authors feedback as well.
As for your posts in the character pages, it's just a reality of the forum that not every post a person makes will necessarily generate a direct response. It happens to me as well sometimes. You've only been with us for a week and you've only made 11 posts thus far, which isn't a lot to go off. Just hang around long enough and you'll slowly start to build up interest and conversations with the other members.
