Given the Question and Answer pair, detect whether the answer is acceptable or not. Denote acceptable answer as "yes", otherwise denote as "no". An acceptable answer is consistent with the context in question, detailed, long, and uses general knowledge of English. Answers that are not definite and suggest a variety of options are not acceptable answers.

[Q]: Question: Is the following correct, or is there more to it? "I forgot his name" I knew his name, but I forgot it. "I forget his name" I keep forgetting his name. Where using "forget" basically means that you tried to remember this information before as well, but you couldn't then either. 
Answer: I forgot his name means I've permanently forgotten, while I forget his name means I've temporarily forgotten even though I expect to be able to remember. In a few more minutes I'll probably remember. See also the phrases "slipped my mind" or "the tip of my tongue".
[A]: no


[Q]: Question: Whenever I hear statements like "It was a great deal for he and I" and "Call Karen and I in the morning," I die a little. Such solecisms, as Twain said in another context (Cooper's prose style), "grate upon the fastidious ear." Moreover, I know that these things will likely become accepted usage in time, if that hasn't already happened. As someone who tries to be careful with words and speech, I feel almost a moral obligation to hold the line against this kind of decline. I'm not a word snob; I say "ain't" when it works for emphasis, and so on. I've tried suggesting the grammatical alternative to the above constructions, but even when I phrase my suggestion in the gentlest possible way it never works well and I almost always wind up feeling pedantic and priggish at best, and at worst I feel I've alienated someone. What's the general opinion here? Is it best to just let these things slide or to take up the fight? In sum, is there a good way to promote good grammar, or at least protect it from the most egregious violations? 
Answer: Does the grammatical faux pas compromise or endanger the communication, or is it merely annoying? (Annoying to you personally, of course. The speaker, and no doubt many others are perfectly happy with it.) Language can be a delight, but it is also, and to many, merely a means to an end. If you are with friends who enjoy language for its own sake and who want to improve their understanding and usage of it, a courteous and appropriate correction will be appreciated. If you are with strangers or persons with whom you have only a business relationship, then as long as the communication is not jeopardized you're probably best advised to bite your tongue and realize that you are a member of a small minority. Unless, of course, you really do wish to be viewed as a snob.
[A]: no


[Q]: Question: I would tend to write double-l, but Google gives me more single-l, so I'm guessing it's an Atlantic divide thing. And I guess all the other *full words. 
Answer: I would say successfull is a typo. Neither Merriam-Webster nor Wiktionary mention it as an alternative spelling. The British National Corpus has 10695 cites for successful and exactly one for successfull. According to OneLook, 33 dictionaries have an entry for successful, but only Wordnik has a few cites for successfull (without a definition). Edit: by popular request, I will add that the adverb successfully is written with two L's. Successfuly would be incorrect.
[A]:
yes
