Well, it's inevitable people are going to get a bit frustrated at having their routine broken up like this after being used to episodes of the show arriving in usually timely fashion, I know I am. I appreciate the work that the subbers have put into this series, but does that mean I'm not allowed to be annoyed when, right at the finale of the series, the episode doesn't turn up until about a week late?
I'm not going to lose sleep over it or anything, but I can understand how others might be getting a little impatient at this point. So show a little compassion, we're getting antsy about our fix here 
No, you can't really be annoyed. That's the point. Well sure you can be annoyed, but you can't walk around asking about it and complaining about it. If these people work for nothing, what do you expect? You should be happy you have actually had a routine in the first place. A lot of groups are all over the place you know. Complain all you want, but what happens? Nothing. The episode will come out the same time it would have regardless of any complaints, unless it's delayed further.
Do you think sub groups are unaware of the fact that people want to watch their stuff? Haha. You cannot whine about stickies, or any other announcements, it's up to the group. They are the ones working their arses off, and all they get is people complaining about their delays and the fact that they don't tell everyone what's going on. I'd rather they focus on subbing, and I will wait until it comes out. As soon as someone mentions the word 'unprofessional' or implies they are that way, you know to stop talking right then. If you want this stuff done 'better', join/make a subbing group. Or pay a current group. Otherwise sit back and watch for free like you already are, and stop complaining!
