So, if you want to create your own site with geographical information, you have another way to input the geographical points now. And if you have a GPS trace of one of the bicycle trails on this site, or a trail I haven’t added to the site yet, I’d really appreciate it if you shared it with me. Thanks!

• As documented on the Google Maps API site, in order to get Polylines (the route map lines) to work in IE, you have to add to the HTML namespace at the top of the file, and also you have to add a special style section. The style section I had already added, but the HTML namespace I hadn’t. Getting the namespace added to the admin screens meant modifying core WordPress code (something I’m not afraid to do). I did file a bug report so that the change could be added to a later WordPress release (with any luck, 2.2 due out later this month).
• IE doesn’t execute Google Maps’ JavaScript scripts correctly if they are inside of <div> elements. So I had to move the JavaScript that makes the maps to the end of the file, requiring plugin users to make an additional theme modification.
• Global variables are not recognized inside functions in IE sometimes; I am still not sure why or when, but I ended up having to create functions rather than trying to use global variables.
• IE got confused when there was a JavaScript variable and an HTML DIV element with the same name, so I had to rename some JavaScript variables.
• I had a syntax error where I initialized a variable to Array() (should have been new Array() ). FireFox did not flag it as a syntax error, and did what I meant, but in IE it didn’t work correctly.
