I doubt they only let a person Like a post once and don't count otherwise. Were I you (I'm not, of course), I'd Like all the Healer related questions just so they are more likely to at least acknowledge it, since there's no limitation on how many you may promote. The only reason not to is if you'd rather them not even consider the option, to the point you'd rather risk them not considering Healers at all. An odd position to me, but we're different people. Moreover, I was just saying that was my post and that I didn't suspect it would have much support. It wasn't a secret reverse psychology attempt to get any.
