Well, JJ Inc., if you have a blog, you don't need to place links in the content of the article. It's enough to set it in your profile and V7 will display it automatically on the left menu bar, under your avatar, as you see at chicgeek. Besides, after only 4 posts you cannot expect the forum administrators to tolerate self promotion.
I do find your piece of advice useful. In a SEO / SEM world, it's nice to be reminded of the power of a simple "thank you".
