I would urge Karl and others not to post something on the Forum then just delete it without explanation. It can become confusing and especially if the post attracts some responses.
Sometimes posts can be on the forum for a while before others notice and react to them. Deleting a post without explanation after just a couple of days goes against forum protocols, unless the post is factually wrong or breaches copyright laws etc.
I noted Puchi's glider and was very impressed with it but had not commented before he removed the post.
