We reserve the right to judge as we see fit what is infringement or not.
You are allowed to quote, if you do so properly. We will edit your quote if you quote more than necessary. Usually, quoting is used if you are arguing a point and wish to reinforce it with a quote. Do NOT quote just because someone asked for a rule and you want to provide it to them with a quote instead of directing them to a page number.
For instance, if you're arguing that Mind War requires line of sight, you can quote the Mind War entry where it states line of sight is required. However, if you get someone asking "How does Mind War work?" then you will just tell him to go to his Eldar Codex, and not use a quote to get around the copyright rules.
