(1) Webpage and website should be one word. That makes them easier to type, and to read in bookmark sites such as http://del.icio.us/valco my account at http://del.icio.us (I invite to share my bookmarks on science, education, on-line learning, and other topics I collect for my blog and website.)
(2) Maybe I just do not know the right shortcuts, but how do you type the sentence punctuation after a link? For example, look at the sentences in Living Machines above. I placed periods and commas after making the link, spacing, then backspacing to place the punctuation. Since the typing was originally in Word, the link was hyperlinked automatically once I spaced after typing.
(3) Typing chemistry formulas such as CO2 is not actually correct. But, I see it often in .pdf and other files where it is just too cumbersome to use subscripts. Superscripts are also difficult. Will a new grammar rule result?
