Huh? Trying to follow six part email welcome, but can't

I already asked an introductory question after opening up a new account. I got all the response emails about having set up my account successfully.

Initially, my first question was tagged as spam by your robots. I received an email saying it was removed. I responded asking about that. I got a quick answer back removing that tag and letting my question post.

OK, so I began getting welcome emails. I’m trying to follow them. The first thing was about adding something to my bio and maybe handles to accounts. But, there is nothing like what the emails say. I logged in, as the first one said to do. I went to My Account Profile, also as instructed. There is nothing there where I can add a bio or handles.

So, huh? I’m confused.
