WordPress MU

What EXACTLY should divide ping sites in ping options?

Coma? Space? Dot? Slash? Anything else?

I saw in several topics several opinions from different users.

Please finally clarify this subject?
Thank you!

new line

Can't be new line. It's only a line to begin with, not a field.

i think it;'s just a space.

That's the kicker, it's looking for a new line separation just as it doesn in WP.

However, since you can't set the value under "writing" like you can in WP, and there's only a text field in the Site Admin editing area for an individual blog, you essentially get 1 entry.

My "best guess" at the moment, as I've looked into this myself recently, is that it's set up this way to conserve bandwidth and server resources. A single ping to pingomatic is much easier to bear than 20 pings to individual services. Which makes perfect sense in the big picture of what MU is for.

It would be nice to at least be able to add additional services though, for special occasions where the need arises, on a blog by blog basis.

So the answer is?

I am not lazy to check all that dividers, just need to know how? How to track?

Or maybe developers can say their word?
Unfortunately I am not kin on coding, so can't check code to find the answer.

As per my first post the answer is:

new line!

:)

change the text input to a textarea so you can put in new lines.
