If basics like Recruitment (which impacts MOST people who have hearing loss) aren't covered in those classes what is? (and what would be the benefit you you taking it so many times ?)
Basically Bill, it comes down to this ... post about things that you know for certain about - and don't make presumptions about things you're ignorant about (just like I don't go posting about specifics regarding CI, or deafblindness etc because I don't have the knowledge that a CI user or someone who's deafblind etc can provide - I'm "guessing", they "know"). Posting "guesses" when people ask questions doesn't help them, it just sends them down a wrong path. Arguing with people who are familiar with a specific technology/condition/language about it's use, validity etc is only worthwhile if you are also educated/up-to-date etc on that topic yourself.
People come here to learn about things- and while it's true that any member can post anything (even if they have no clue what they're talking about) ... it's much more HELPFUL if people who post an answer actually KNOW about various topics post valid helpful information, instead of posts consisting of "I guess", "I read in a 20 year old book", "I've never used this, but maybe...." etc.
