I was looking for a tab I wrote a few years ago, but it wasn't showing up in search or on my account. I found it with Google, and it definitely exists, but it's not accessible from within harptabs.com. I thought this thread would explain it, but I checked archive.org and apparently that tab has never been included in my account listing, which is weird because I would think I would've verified it was there after posting it; I also don't see why a problem with the user tables would make a tab not show up in search.
The tab is this one: [www.harptabs.com
I don't know if there are any other tabs that have been "stricken from the record," as it were, because it's kind of hard to see what's not there.
