Question

fix any punctuation or capitalization errors below. click \submit answer\ if there are none.
first, we need to get a ton of photos of groundskeeper willie and the mayor second, we have to post them all on facebook.

Explanation:

The sentence has two independent clauses ("First, we need to get a ton of photos of Groundskeeper Willie and the mayor" and "second, we have to post them all on Facebook") that are related in a sequential list. A semicolon is appropriate to separate these two main clauses in a compound sentence, and "second" should be capitalized to match the capitalization of "First" as it starts a new part of the sequence.

Answer:

First, we need to get a ton of photos of Groundskeeper Willie and the mayor; Second, we have to post them all on Facebook.
