Nope - I haven't been in any signature campaign for at least twelve months and had to reluctantly turn down an approach via P.M. just recently as I'm only posting about half of what would be required.  I try to post via the mobile app when I'm out and about.  (Doesn't always happen that way, but still...)

Today, the humble three stairs near where I live got a work out today - down/up/down, then a few minutes later up/down/up making my today for today 12 steps.  (not counting my ~3 klms walking)

Walk on!

(if a participant isn't walking on the stairs could they be said to be perched on the Mezzanine Floor?)
