When you use neither in a sentence, use nor to follow it, not or. Or is usually use to follow either. And while in the process of using neither-nor, the verb following neither must be in present tense. It is because neither is already negating the verb and so using past tense would be unnecessary and it is not the proper way to do it.
I understand that you might find this grammar 101 as something stupid but then again, I find it necessary for a few people. And they really need to get themselves back to grade school. They can’t even construct a single sentence! 😉
