I accept Dragoness’ offer #3 to look at rule 4 in exchange for looking at Rule 19
NAF, your accept is disallowed because you didn’t say what you wanted.
I’ll be PM-ing for this one shortly. May disappear for a lot of the afternoon because I need to get some actual work done. 
You can pm amongst yourselves. (I hope I don’t run out of PM space!)
PercyPercy Offer 3 I will let anyone see rule number 6 in exchange for an L, P or any vowel.
I will accept USCDiver, and NAF’s offer once you tell me which rule you want. Re-issue offer #3.
I’m signing off for a bit, but I wanted to repost Dragoness offer #1: I will give Omi No Kami a look at rule #13 (or 4 or 5, if you want) in exchange for a look at rule #14 just to make sure Omi sees it. Come on, Omi!
Question: Can you offer rules you’ve only seen, and don’t have? I mean, could priceguy or Doctor Who help me out on Rule 14, if I made them an offer?
You can’t accept NAF until he says what he wants. 
No, nobody who doesn’t hold 14 can show it to you.

OK, so I seem to be bad at this.
Accept Dragoness offer #3 to look at rule #4 in exchange for a look at my rule #9.
A clarification - this was asked me in a PM, but I think it’s a fair question to be answered publicly.
There are many ‘spelling bonus rules’ in the set. The same letter may be used for multiple spellings - ie, to spell out two different works with a K in them, you only need one K, not two.
Hal Offer #2: Hey, NAF, trade you a look at Rule 5 for a look at Rule 3?
Accept Hal offer #2 We can just PM each other?
Counteroffer: I’ll trade percypercy a P Card and a look at Rule 15 in exchange for a Y Card and a look at Rule 6.
You’ve both been pmed.

NAF offer #2: Uncommon Sense I will offer you a look at rule 3 for a look at rule 2
Doctor Who Offer #4: Open to: Hal Briston, MadTheSwine, or billyb0b - I will TRADE you (not show) all four of my rules in exchange for you giving me (not showing) all four of your rules. Offer only open to one acceptance.
Power play men. Hardball.
Doctor Who Offer #5: NAF1138 - I will trade you my P card in exchange for your G card.
No can do good Doctor.
NAF offer#3: Doctor Who I will trade you my G card for one of your rules and either your A card or your E card.
Counteroffer I’d like a Z and a look at rule 15 in exchange for the Y card and a look at rule 6.
Oh, I’m afraid I couldn’t possibly. Thank you though.
Alright, get back to me if you think we can strike a deal.
Revised USCDiver Offer #1 (in order to avoid any conflict with other offers) I offer to give Hal Briston a look at Rule #19 in exchange for a look at Rule #1
Sorry, I have no Z Card. If you choose, my original counteroffer still stands: I’ll trade percypercy a P Card and a look at Rule 15 in exchange for a Y Card and a look at Rule 6.
