I've tried MANY times to link my subeta account to subetahq. Never works. I take the code, stick it in the profile box, hit enter, click next step. Then I get some stupid error message saying I didn't put the code in (which happens to change). It's quite frustrating.

You need the widget section added to your profile (that's where the username and code will go). Detailed instructions on how to do this can be found by clicking here.
