search), I?m hosed. accessible, but still: the archives may be organized by date, but the useful, no? talking about? (I don't know the tools/sites you mentioned.) Sven, Take a look at the sites I mentioned. They're pretty clear how they work within 5 minutes of poking around, but basically what they do is provide a very organized question-and-answer forum. Users ask questions, can include pictures or code, and any other useful information. Other users are free to provide an answer below, and users can add comments to both questions and answers to get further clarification on an issue. They also include features like "upvoting" the most helpful answers, so that users can find a question similar to their own and the best answer will be sorted directly underneath it. When users type in the search bar, or start typing a new question, the site (very cleverly) suggests previous questions that might be helpful. They also make very efficient use of tags to point users in the direction of related answers. For me, my learning curve on LaTeX has been significantly shortened as a result of this format. Trevor
