I feel that there are two parts to this and both of them should make you feel welcome:
###Asking questions
Asking questions
As a person with Asperger, you should feel welcome to come here to ask about dealing with people in your life - considering your diagnosis. I'm sure there are many questions that you may have about how to interact with non-Asperger people. I encourage you to use a tag to classify your Asperger-specific questions as some people may have experience dealing with this and have specific advice.
###Answering
Answering
Particularly in questions about individuals with Asperger wishing to interact with non-Asperger people or the reverse - a non-Asperger person trying to get advice on how to interact with someone with Asperger, you should have a great deal of insight into these - particularly in the case of the latter. While not all Asperger people react the same, personal experience is always welcome, particularly when supported with data.
###Non-Asperger related posts
Non-Asperger related posts
As it relates to other topics, the guiding rule of SE is to show your work, support your claims so if you want to help answer questions about general interactions, please feel free, particularly if you can support your responses. Much like on English Language Learners, even people learning the language are welcome to write answers. The community votes on every post to show whether they support the answer or not. If your answers are off-base, the community will likely down vote them but that tells you a lot, too... Please don't silence yourself because of it, though... consider what you're told in response to your posts and think about it!
We welcome answers from everyone as long as they are willing to accept that others may not agree with them.
