Citing Articulate and products in a blog post
What is the protocol when referring to Articulate and/or Articulate products when writing a blog post. Specifically, what is the criteria regarding the necessity (or not) of using the Registered or Trademark Symbols?
Articulate®, Articulate® Quizmaker, Articulate Engage®, Articulate® Online, Articulate® Presenter, Articulate Storyline®, Storyline®, Empowering Rapid E-Learning™, and Empowering E-Learning™
But I've referenced Articulate in my blog, for example here, and I wonder whether I should be including the symbols. Also, am I violating and protocol by saying "Articulate's Studio Suite" rather than Articulate® Studio Suite (I know for example that Microsoft doesn't want references to look like the former).
Any guidance is appreciated.
Oh, and by the way, why in the info provided by Articulate above is the register symbol sometimes after the product, as with Engage and Storyline, but mostly after the word Articulate?
