Please do not offer my tubes individually or completly to download.
My tubes are available for free, so please don´t sell them.
It is not necessary that you set a link to my side if you want to use them for letters, pictures or other.
An inquiry for the use in Tutorials is not necessary. Indeed, then I would want that you set a link to my side, so that the download starts from my blog.
