Don't give yourself such a hard time over it my man. The same thing happened to me a few years ago when others were running the draft because I wasn't in a very good place, and I spaced on the date. I was sure it was one day, but it had been the day before. Life happens sometimes, it's all good. You're a member of the family, we're not gonna kick anyone just because they mixed up a date. You can make your make up picks either here or in the draft thread. Other than that, just forget about it and focus on taking guys that make us all look like idiots for passing them over.
Also, Cliff Ronning was the autograph that I got for my brother when I was a kid at the old Pacific Coliseum. He seemed scared to go in the group of kids to ask, which was weird considering he gives literally zero f's about hockey and always has. But I'd gotten Gino Odjick's for myself so I took his book to get Cliff Ronnings for my brother. We were only at that game because my cousin was playing in the little minor hockey game they have between periods. Ironically, Cliff Ronning's autograph was the only autograph my cousin successfully got. I managed to get Geoff Courtnall's autograph, but he was about to go inside and he hadn't signed my cousin's card yet. So Scott ran to the door and stood in front of them blocking the way and declared "you're not getting in until you sign my card!!" So he did get Geoff Courtnall's autograph as well but my aunt confiscated it and she was so embarrassed and angry with him that he wasn't allowed to get any more player's autographs for the day.
