How did you format the form you filled in with adamsnames? I've sent an email to their "robot", but haven't gotten a reply yet. Can you show me how your registration email looked like?
Then I just pasted in this entire form: http://adamsnames.tc/register/short.txt
Here's a modified example taken from a real one I submitted that got a response right away: http://paste2.org/p/29938
Two things to consider: Last time we bought domains (ri.ms and oh.ms) was in January. Also, we got a notice that they may not be selling MS domains anymore. If seeking .ms nowadays, the robot might not respond, I'm not sure.
