+rep for help
You'll also need to have been repped at least +1 to see any you've received (the 10 rep you start with won't be visible until then).
Well yeah, but I saw in my notifications I got repped like twice. Thanks guys! I'll +rep the first person who helped. Idk if it's allowed or not to +rep every single person
The rep notification is always '2', regardless of rep # (be it 1 or 10).
And you are allowed to rep anyone you see fit until you're maxed for the day. Just be sensible and don't perform rep abuse without reason, only that's disallowed.
