There's an old thread for newbies and their ?s. I used to have it bookmarked before I sent my laptop in for "fixing". It's now on a disk but who knows where, I don't.
Check out the homepage and click anything that looks like it might be it.
The ping is really just symbolic, in a sense. Any time you post a reply - IOW, a comment that has another FR member's name in the "to" box, is a ping. It draws the other person to it in a remorseless magnetic manner.
:>)
Getting a "ping" via a pinglist just means many people were pung all at once.
Crystal clear now, I'm sure.
If I find a link to that thread, I'll ping you.
Are you referring to the FR html sandbox?
