I have a special ed background, in the areas of learning disabilities, Autism Spectrum Disorders, and Other Health Impairments such as ADHD. I wouldn't say I steer clear of replying to certain areas. If I have something to add, even if I don't have as much experience as others, I'll put in my two cents. I figure people will either agree or disagree with me and that's perfectly fine! Take my suggestions or not! That's okay!
