There was some kind of bottleneck or something with the MPOS system at the official pool.  I was finding blocks, but they were not showing up on the MPOS blocks page.  And with the temporary delisting at iSpace, I think lots of people weren't opening their wallets anymore.  So I decided to let it continue for an hour or so with my S7, and it did finally break through whatever the logjam was.  Either that, or someone finally read (but didn't respond to) my emails/inquiries.  Or maybe it's a really slow system that only updates after a large # of blocks, to conserve cpu cycles...  

I have still not received any sort of response back from the official pool -- even though I sent out emails from within the system, as well as an email to the support@domain and even the admin email registered with whois.  So I am quite happy to find out that iSpace has added it back in.  At least they answer email.  

Thanks for your reply, by the way.  It's appreciated.
