A few things you need to know before you use this forum :
1/All expressions here were created by people who deserve the credit for their work, so please make sure it stays that way (in other words, nobody should use these expressions for any other purpose than his own work)
2/The way things are organised for the moment are through a "problem-solution" construction : state a problem - here is the solution. Feel free to present things in this way, or in any other way, but always make sure the expression is highlighted and its purpose is clearly stated
3/This forum is essentially made for posting expressions, so please don't create too much discussion about the expression itself. Let's keep things clear, so make sure discussion about these expressions goes into the discussion section
4/The rest is up to you!
