There is a minor bug, or perhaps misleading information in the FAQ page which caused me a major amount of frustration.
I wanted to change the Visitors line.

FAQ describes:
    * viewers=0 This is the text label on top of your counter. "0" is the default, which will say "Visitors" on the top of your counter. "1" will say "Viewers" and "3" will remove the label entirely. Any other value which includes letters (a-z) or numbers (0-9) is acceptable, as well as plus signs (+) which are converted to spaces, exclamations (!), periods (.), and commas (,). For instance, if you'd like this to say "My Flag Counter!", you'd change this to be "viewers=My+Flag+Counter!".

Reflecting, it's technically correct, but it misled me and might have a similar effect of other users, reducing their satisfaction with FlagCounters.

The example:
For instance, if you'd like this to say "My Flag Counter!", you'd change this to be "viewers=My+Flag+Counter!".
I tried replacing viewers=0
with:
"viewers=My+Flag+Counter!".
viewers="My+Flag+Counter!".
After viewing source on Milinda's site I now realize it must be:
viewers=My+Flag+Counter! -----WITH NO QUOTE MARKS!

You might want to add a comment to that effect.
Thanks,
Bob
