I'm running the Google-Sitemap Generator plugin for the first time, and it's been going for about 45minutes. It looks like it's working, but it could be stuck in a loop I suppose. Hard to tell. Browser status bar looping through...
Read [MY DOMAIN] (~15 seconds)
Stopped (less than a second)
Connecting to [MY DOMAIN] (less than a second)
Waiting for [MY DOMAIN] (~1 second)
Transferring data from [MY DOMAIN] (less than a second)
Then back through that whole loop.
