I have a friend that works for the "for dummies" corporation and I asked him about any books that they had for drupal. He told me they just got a new one in, so the next time I saw him he brought be a book called "cracking drupal, a drop in the bucket" (US $40)

I have yet to read it, but as get farther along in the website I am building I will be going through the book and learning ways to keep people from hacking my website.

While reading the book, if important issues I feel should be dealt with (especially for a community site) come about I will post them on here so everyone knows how to keep your site safer.

Also it may not be a bad Idea to add a "security" category here. I feel this one of the most valuable information a community website can have, especially in todays sue happy society.
