The cafeteria is dark except for one light in the kitchen. The cafeteria manager is in there, counting lunch money. She says that there were some strangers in the school today and they ate lunch in the cafeteria. "They paid cash and ate their lunches. They didn't even put their lunch trays up and wipe off the table. We even found their receipts on the floor!" You pick up the receipts, thinking they might be a clue. Look them over carefully. Check over the numbers and letters in every direction. Hackers love letters and numbers because they are a part of writing code!
When you figure out the clue, go back to the home page and enter it into the hackers' database.

My favorite is "be concise."have you ever received an email and had to read a page full of information? by the time you finished reading it, you had to re-read it? i have even hit "reply" so that i could break it down into separate paragraphs and send it back to myself.what is concise? get to the point, fast. when opening an email like this, some will close it or print it to read later.i learned to use the subject line to prepare the reader for content. such as, "need on (blank), " "info only re: (blank)," "request input on (blank)," "read before (blank) meeting." these are just some.if you are asking for something, make that your first sentence. follow this by who, what, when, where, and how. use these, as necessary. example; (1) who (who needs it and or who does it), (2) what (specific description of what is needed), (3) when (specific, i need this by 8: 00 am monday or i need this by 10: 00 am today), (4) where (does it have to be printed and taken to someone, maybe the place of the meeting), (5) how (i need it scanned or faxed back to me at this email address, provide me with a hard copy).do not send yet. re-read it. did some spell check change a word? maybe let someone else read it for understanding. you want to avoid multiple emails asking for clarification. if important, put a read receipt on it. you will know it was opened, not necessarily read.end with a you.
