Bubble Junky:
Actually, 'English' is a pronoun, and as such, should begin with a capital letter.
This should say 'I think that it's a preposition and you shouldn't end a sentence with one.'
Pot & kettle ?
Well, I think "that's" means "that is" and "I think that is a preposition" works. English is a proper pronoun, which is why it needs to be capitalized. "He" is also a pronoun but does not get capitalized unless it is the beginning of a sentence or a quoted passage, or is part of a title, or refers to God. I think you're jumping on me because you feel belittled by the PADI/Help thread....but I'll humor you.
First off (really, I've already made some points, so this shouldn't be first....) I wasn't really upset with the OP for his small grammatical mistakes, as we all make them and it's ok. I just dislike when people use the wrong word, or misspell a word in such a way that they spell another word correctly. For example, when someone says "It would be so nice to meat you!" They misspelled the word, but spelled another word, a homonym, correctly. You will notice that I went on to provide some valuable advice to the OP, which was the real purpose of my post.
Secondly, you missed several other errors. I did not capitalize the beginning of my second sentence, or the beginning of my second paragraph. If you are going to lambast me, atleast give me flack for every mistake I make! I mean, if you are going to patronize me, do it right!
(I do not advocate DIR diving, only DIR lambasting and patronizing

)
To the OP: DANG! Your thread grew! I'm sure someone has answered the "what is Craigslist" question already, but just in case it was glossed over, Craigslist is a type of online community. It's almost like a giant bulletin board--anyone can post to it, anyone can read it, no "membership" or "signing up" needed. Type in "Craigslist" then on the long list of states, find your state. Then find the closest city to yourself. Once you know this, you can google "Craigslist ___________" And inthe blank, put that city name. I google "Craigslist Gainesville" to find my local Craigslist. On Craigslist, you'll want to find the "sporting" section, but sometimes people mispost, so it'sbetter to search for "Scuba" or "diving." There you can find people who are selling equipment in your town, so you can go pick it up and test it out before you buy, and you don't have to pay $20 for it to be shipped to you.
