For security reasons we don't discuss the security features however they will end relatively quickly. We need them to prevent spammers and other undesirables from gaining access to the site and there is no reason for them once they served their purpose.
As for links, I always assume that member may not have had the luck in finding what I found so when the link is appropriate, I always provide it. The ones above are greeting links that we give to everybody when we spot them. This forum is heavily moderated so making member aware of the rules makes our job a bit easer. I say a bit because I suspect often the links are not read.
