apache log errors -- help

This is over my head, although I can probably do whatever you tell me I need to do to fix it.  I have the following errors:

[Thu Jul 24 10:11:34 2008] [error] [client **.**.***.***] File does not exist:
/home/***/public_html/plugins/tiny_mce/plugins/contextmenu/css/contextmenu.css

[Thu Jul 24 10:11:35 2008] [error] [client **.**.***.***] File does not exist:
/home/***/public_html/plugins/tiny_mce/themes/advanced/css/editor_ui.css

[Thu Jul 24 10:36:56 2008] [error] [client **.**.***.***] File does not exist:
/home/***/public_html/robots.txt
[Thu Jul 24 12:32:06 2008] [error] [client **.**.***.***] File does not exist:
/home/***/public_html/robots.txt

[Thu Jul 24 12:40:27 2008] [error] [client **.**.***.***] File does not exist:
/home/***/public_html/favicon.ico

None of the file exist on my server nor in my downloaded copy of dolphin.  Can you tell me what I need to do to get rid of them?  Thanks in advance for your help...

Just create the indicated files to stop the errors.

robots.txt is actually a useful file which you can do a search on the internet for
to find out more.

Just take your favorite icon file and upload it to your root and rename
it favicon.ico to stop that error.

ok, thanks, easy enough!
