encryption or password protection

Thanks quant for your excellent explanation of my approach. I couldn't have done it so well myself. I also marvel at Jan's perseverance. It's a great asset not many can put into practice. The trick is in the template theme. Once the user understands how template works in UR it'll be noticed how easy it is, but not quite clear to grasp. I hope Ultra Recall will some day provide a way of its own, although this approach has some interesting advantages .
