That's why I use w3 Total Cache from Frederick Townes. You can minify and combine stylesheets and javascript files, even serve them from a CDN.

Pinging is separate from the WordPress theme. Install the cbnet Ping Optimizer, enter the ping list, and set your Pinging settings. This doesn't require any coding. It should just take a couple minutes.

Haha, gotta love those moments. I'm glad you got it working.

Did you add the code to your functions file? Make sure you are using the right name and value. Using only the video ID in the value field, not the whole url. It could be modified to parse out the rest of the URL, but that would take some regex, and it's easy enough to just use the ID.

Tim, if you weren't a real freind, I would think you were spammer! At least you didn't type it with your face . .

A great use for it is development. Just use subdirectories and you don't have to worry about wildcard domains, Unless there is a reason you want to use subdomains.

I prefer to use subdirectories for most multisite uses, but this is a nice guide for subdomains. Some hosts seem to need to enable wildcard domains. Maybe for those using a different host this may help.

Lauren,

The first time you use a custom field, you need to click "Enter New", under the drop down for the custom field name. For this custom field, type "tube". In the "value" text box to the right, paste the id for the video. Click the "Add Custom Field" button, and you're done!

Custom fields are basically key(name) - value(value . . ) pairs. The php you paste into your custom_functions file tells WordPress to print YouTube embed code into the feature box if a value for the custom field with the name "tube" exists. It uses the YouTube ID you paste at the end of the url within the embed to select the video.

Let me know how this works for you.

Thanks for letting me know Otto. I'll edit this post as well.

Keep up the great work.
