How you should use the terms Spikeball™ and Roundnet
Spikeball™ = the brand. Roundnet = the sport.
Here's a little Q and A to clear things up:
Q: Can I say something like, "Let's go play Spikeball™ "?
A: It's better to say roundnet. If you're referring to Spikeball™ brand equipment then sure, that can make sense. If you're playing on a different brand of roundnet equipment and calling it Spikeball™, that's wrong. It's just like if you said "let's play Nintendo 64." It's okay if you're about to face off with Bowser but if you're collecting rings with Sonic the Hedgehog then it's wrong. If you say roundnet you'll never be wrong. It's one of those - a square is a rectangle but a rectangle is not a square - sort of things.
Q: Can I use Spikeball™ in the name of a club, group, or team I'm forming?
A: No, any club, group, or team not officially associated with Spikeball™ Inc. should use the term roundnet. Since Spikeball™ is our brand name it can't be used in an official capacity by another organization unless we give written approval. Imagine someone opened a Crossfit Gym without actually going through the proper franchising process...that'd be a no no.
