All, heads up. gmail doesn't like me :( I see Steven's and Ihor's replies in lore, but nothing in my mailbox. And Steven's reply was a couple hours ago. Nothing in my spam either, and I was cc-ed directly! So it's not mailing list delivery throttling. Ouch. If it looks like I'm ignoring your emails, it's not me. It's gmail fault. ^ permalink raw reply [flat|nested] 5+ messages in thread
