If you're in the USA, and protecting a service branded through associated advertisements, illustrations or sounds, you get a service mark. They're effectively the same as trademarks, just applying to different classes. WikiFur is a registered service mark. The term used to identify an unregistered service mark is SM, rather than TM.
And about those classes: there are 45 of them, and a trademark will only protect you in those you actually use. So, you might bake a cake or print T-shirts saying "Anthrocon", and as theirmarks are only registered in "Educational and entertainment services, namely, providing motivational and educational speakers", it would be harder to prosecute it as a trademark violation (but it might be viewed as passing off, especially since Anthrocon does print their own T-shirts). In addition, if the actual "paw in Anthrocon circle" logo was reproduced, it would be a copyright violation.
You also can't just think up a name, register it as a trademark, and never do anything with it, like a patent. You have to actually be baking cakes, or at least be planning to (and subsequently provide proof of having done so for protection to continue). That's because what's being protected is the goods or services that the word, image, sound or scent represents. No goods or services, no protection.
