Just noticed it and don't know whether it's a temporary system glitch, but the option to thanks/no thanks me is presently MIA. Did I inadvertently disabled something or what?
FWIW, tried to thank roymiami for a post upon seeing there was no option to do so (he might have disabled it himself, dunno), then checked on mine.
Working for me, Vaark. Sometimes you have to refresh the page to thank newer posts
