ArcadeBlizzard6, threads are locked by the moderators to prevent future posts. In the case of Peter Lerangis' tour, IMHO, it was locked to prevent a flood of 'Yay' (he's coming here) and 'Nay' (he's not coming here) posts. Religious discussions might also be locked.
Also, there have been lots of questions about replicators:
From the site Help page, you can get replicators by Completing Clues, Solving Pook Puzzles, and from :
You can find replicators in Card Packs. You can get the most replicators in Card Pack 4, because every copy of card Pack 4 contains the Ultimate Replicator, which is worth 10 replicators.
(Note: The help page is really helpful. If you’ve read the page and still have questions, near the bottom of the box on the right is ‘See all FAQS. If you click there, you can search for the topic on the next page. Some of the pages haven’t been updated for Cahills vs Vespers (such as agent ranks), but most of the info is good.)
It's been a while since I've used a replicator. What I did to use them effectively was to look at all of the cards I needed. Each one will tell you how many replicators will be needed or if it can't be replicated. Then, I looked at the card combos to see how many I needed to complete them so I could get a clue for the clue hunt. Redeem those first with replicator cards before doing stand alone cards. Be sure to look under 'The Clue Hunt' tab under ‘My Cards’ for the combos. Hope this helps!
