Welcome to Fedora! I'm glad to see you here (even if it's not for SUSE
things). I'll be happy to review your package and sponsor you. :)
Well, this initial package (s3fs-fuse) is personal stuff (that's the reason I am using my personal email account and I am doing during me free time), but of course that doesn't mean I can't collaborate as SUSE employee in other cases. We will see! :-D
I hope you enjoy participating in the Fedora community!
