The format of the post is to be fixed, this is a bug in the forums at the moment.
Some of the older links are not redirected properly at the moment.
Tom is aware of it and is working on fixing that issue as well.
If you try to click one of the most recent links (generally down in the list for behaviors or plugins) you will see that they do take you to the appropriate topic.
Please be patient while this is getting fixed and will get back to normal usage as soon as possible.
