Since we have lots and lots of videos here, you will need to know the best way of finding what you are looking for. Each post has the video(s) of the topic it is about. Many times there will be more than one video that is a continuation of the previous one. These videos will be posted together within the same post. To find what you are looking for, either use the search box or the list of categories posted in the right column.
The IQ system is constantly evolving, so please keep in mind that some of the older videos may show features that have been replaced by newer ones.
