...without strangeling the community? I've been avoiding the KOTOR forum to avoid spoliers but I still run across them since people insist on making the title of the topic a detailed sinopisis of the actual post. It'd be nice if I could somehow avoid this. Either by enforcing some rule or better yet being able to filter out new posts from sections I don't want to see.

By virtue of the fact that you're visiting a message board relating to certain games, spoilers are inevitable.

I don't think you can really expect to not be spoiled while reading forums dedicated to a certain game... Once a game comes out, I think it's possible to structure forums into spoiler and non-spoiler content, but pre-release you take your chances.

Also keep in mind that what you are hearing about and what you see on your computer may be different as comments and reality do not necessarily coincide.
