We have had several enquiries relating to the three 'snipurl.com' website addresses in the opening paragraphs of Matthew Hutton's article 'Past, present and future' (Taxation, 2 August 2007, page 139). Unfortunately, we did not appreciate at the time that a figure 'one' and a lower-case letter 'l' would appear the same in the text of the magazine. The first character after 'snipurl.com/' is therefore a figure 'one' and not a letter 'l'. We have made a note to ensure that this is not repeated in future 'snipped' URLs.
