Every member has a rank (from post count), reputation (from other members) and a trust level.
Ranks grow as you post: Newbie, Junior Member, Member, Senior Member and up.
Reputation blocks fill in as people thank you for helpful posts.
Trust levels unlock links, images and signatures as you take part. New accounts start small so spammers can't do much.
Staff are always trusted. If you think your level is stuck, ask a moderator.
