Avoiding Numbers in iWeb Page Names and URL's
Non-Roman characters aren't recommended for use in
website names, nor are the following: forward and backward
slashes (/ \), brackets ([ ]), tilde (~), exclamation
point (!), question mark (?), "at" sign (@), number
sign (#), dollar sign ($), ampersand (&), asterisk
(*), colon (:), equal sign (=), comma (,), double
quotation marks ("). Using these characters may
result in names with strange numbers in them.
