Ah, man.
These are all adorable.

4634626 I'll start testing some of them here.

4634621 Personally, I enjoy four and five for banner, but that's just me. I vote four for Icon, but it might change depending on how it shows up.
Edit: 2 shows up rather poorly in terms of quality. It's cropped in the wrong portion.

I'm loving the Flufflepuff banner.

4634653 So far I think Octavia looks the best for the banner, then it's between the CheesePie icon and the Rainbow Dash Tail one.

4634657 I agree about Octavia. For icon, I vote Rainbow. Very nice.

4634660 The banner is up.

I vote Flufflepuff for banner and, like Smaug, the Rainbow Dash icon.

4634677 Dash icon is up. Go check out the main group.

4634675 Looks nice. On an unrelated note, we might want to update the admin list on the front page.

4634694 Yes, I was going to make a post later about updating the front page entirely.

4634697 Yeah, it could probably use an update.

4634621 All of the banners are kind of "meh" to me; especially since most of them don't seem like they'll crop well. Out of these ones, Octavia was probably the best choice.
However, I like the Dash icon. It'll be much easier to find threads from the group on my dashboard now.
