How to purify water with iodine? Answered
I found this site while searching for an answer to my question. I read the instructions; I then asked for the PDF copy for future reference. I was asked to sign in, along with other questions. I requested the free membership for now, since I do not know this site. I was then told that I could not have the PDF without paying for membership. Respectfully, I feel that it would be much better to state any rules/requirements before asking for personal information. If you do not wish to share a PDF, that is fine; just make it clear.
Perhaps this is a wonderful, informative site; I may never know. Right now, I am a bit disappointed with my experience here.
