I finally found a way to get a free web site, thanks to information on a diary entry by Scienceboy2. The web site is still a blank page because I'm still trying to learn how to develop it.
Meanwhile, I have done what hermit crabs do by moving into an shell on Yahoo Groups. To find an empty shell, select a group category and go down toward the end where there are groups without any members, messages, files, photos, or links.
Although not very religious, I went to the end of a list for "religion" to find an empty shell at: http://groups.yahoo.com/group/ina56e/ to add files. The subjects of the pdfs are: (bamboo ship models and pop-pop boats) (some mechanisms for bug legs) (dome-shaped houses) (tube-shaped houses) (piezoelectric stuff) and (insect flight mechanisms)
Anybody who is interested in these things is invited to download files.It will be necessary to join as a member, which will take a minute or less. If you decide to "unjoin" just click on an e-mail address that will be sent to your mailbox as an automatic message from a moderator.
Best wishes to all, Frank
