Hello. I looked at the rules and saw that ingredients can be out. With this rule, can I pre-boil water?

Yes, other runs have pre-boiled kettles of water, so it seems to be allowed.

In a recipe book, 'boiled water' would be listed in the ingredients rather than in the steps, so it makes sense that it is allowed here.

edit: spelling and grammar

Another question: I've seen people have multiple people working, but I know runs have been rejected for having multiple people. Are multiple people allowed?

Yeah, they used to get rejected if they had multiple people, but there was no rule explicitly stating you can't have help. After Astralspiff approved herm and her grandmas team run on his live stream runs with multiple people started getting approved. I obviously cant talk for the mods, but if you make sure you credit everyone,e it will likely be fine. I still run solo though, I don't think the time save is that great unless you're perfectly in sync (maybe have someone count or shout directions)

Yeah you are allowed to be multiple people making the pizza
