I couldn't find an easy place to submit a compliment on my interaction with a sales rep. and I saw someone say on a forum that it's expected that that kind of thing should go onto a forum. I argue that this isn't good enough because, as other people have noticed, links to the forums aren't near the top of the website and you actually have to do a bit of looking around to find them. I have little expectation that managers at various levels ever see positive comments on their employees there. Compliments to your sales people and others who work at helping customers should really be a lot more visible than that.
I'm resorting to trying to find a corporate headquarters address and then writing a paper letter because I don't want to just give up or send my compliments into the ether where no one will see them.
