I don't know what campaign you were in since I have signatures blocked and never saw yours, and I just looked at your profile and you obviously removed your campaign signature--but what I was wondering was whether they had a minimum number of weekly posts or not. I've been in campaigns with minimum posts, and I always hated that unless it was a very low number.
Now, I doubt I will be any less active, but now I can purely post for fun without actually having to post.
If that's the case, why are you going campaign-free? The only reason I've been in signature campaigns was because I figured it'd be better to get paid for doing something I'd be doing anyway. It would be like leaving money on the table if I didn't take part in one.
But hey, props to you if it makes you feel more free. By the way, this might be better in Reputation or some other section.
