Slug rules: lowercase, hyphens only, max 50 characters, derived from display name.

2. Name must relate to plugin function The display name must correlate with what the plugin actually does. Exception: original invented terms.
3. No keyword stuffing Unnaturally repeating keywords in the name for SEO purposes is not allowed.
