But maybe you can offer a bounty and post it in the service section? This will most likely cost you something though.
But what I wonder honestly is why people want howto-videos anyway. I find it very tiresome to do something after a video. I have to skip back if I missed a part. And while its nice so see where to click, a picture can have the same effect. Also if I have to type something I cant copy paste it from the video. I actually have to type it. So its limited to clicking stuff.
A video has a certain speed and maybe I am faster or slower. The video part of the howto is just in the way. I get that you want to visualize something and that can be very helpfull, but a video is not the way to do it imho.
There seems to be a trend where someone just makes a screencapture and talks over the steps to make a youtube video.
There are certainly some advantages of using videos over text or static pics.
IMO, it is easier to attract attention with videos and it allows users with zero knowledge or experience to follow the steps more easily.
