Hi Sco,
yes, the MADness issue chain has been around for a while now (about 17-odd months actually), and like other chains it sometimes just takes a while to get into your inbox, hehe.
Feel free to take a looksie in the
Issues Spoilers thread (and ctrl+f to search for "madness") if you want to take a looksie at it, although I'd fully recommend waiting out the surprise :3c
We also used to have a thread for discussing the chain outside of the spoilers thread, but it was last posted in quite some time ago and as such would probably be considered gravedigging at this point.
Good luck where MADness lies.
