It is an excellent, free and open source tool that allows you to ask question from the people to satisfy your curiosity. You can ask anything from the people and get the answers quickly. This is a great tool of use so I have found no issues in it, It is a freeware which can be download and used for a day/one week or one year or more. After installing this you don't require any database if there will not be much data stored here than go ahead with installation otherwise we need to pay some money to host our websites at certain companies. Its easy to handle also just try out once after downloading then rest all works fine. Now everything needs to work without errors if not then please contact us to resolve such type of error but overall i highly recommend it to anyone who wishes to ask their favorite things from others.
