http://www.greatnexus.com/blog/ I am playing with the idea of setting up a blog to be more involved in my community. I have some ideas as follow: 1. The latest blog entry will be feed to the home page (don't know how to do this yet...may be using RSS, but I don't know it yet.) 2. I want it to have multiple author (which the software does support), the return on investment for author is that they get to include a short about author line in their post which can contain live link to their site. 3. I don't know how to use ping and trackback which I hear so much about. Can anyone help me with number 3 for now? Thanks.
