What's the problem with an unobtrusive sig link?

As someone who will probably sign up for a TH account at some point, I will be wanting that 10% discount and for that I'll need someone's referral code.

If I read a particularly insightful and/or helpful post... the codes in signatures will make it easier to make sure my commission goes to someone who deserves it, instead of having to PM them, wait for a reply, blah..etc



tl;dr
newbs need referalls
put yer code in your sig
write something beautiful
impress us
profit
