<p>Hopefully, people will read and understand crazybandit’s explanation. :)<br>
Please note: SAT still considers this usage of “hopefully” wrong. I consider it sub-standard. You don’t want to write things that will make some of your readers cringe; you don’t want to answer “No error,” when the SAT writers believe there is one. You should be using “I hope” or something similar at the beginning of a sentence like the first one in this post.</p>
