The Ask an Expert Category is for websites that allow users to submit their own questions for answers. While archives of answers and information are useful, in order to get listed in this category, there must be a live human answering questions, not just a search engine or computer.
In addition, this category is for sites that provide this human service free of charge. Answers that are available for a fee should be listed in Ask an Expert: For a Fee. Businesses that are trying to promote their services should be listed according to their industry and/or geography. Forums also are not appropriate for this category, and should be submitted to the relevant subject category, as they are a different type of site and have a different function.
Again, we ONLY want web sites where you can submit questions to a pool of experts and have them supply an answer.
