If I'm allowed to crit the Hub Page:
- I'd put the welcome message as the page title, instead of "Hub Hell-O-When21"
- Rules could be put into a separate collapsible
- Write a bit of introduction/flavour text, perhaps also explaining our motivation behind it. You could draw from the announcement, if necessary.
- Needs more public domain Halloween SVGs. Or any other sort of appropriate decoration, really.
Eschew elucidation, espouse obfuscation.
