Welcome to the forums!
The forums are primarily member-driven and not TA Staff.
I had a look at my travel map and see what you mean. When the travel map was revamped, there have been missing cities that needed to be added. There was a long-standing thread but now that the corrections slowed down, you now need to contact TA Staff via the Help Center. So, you can start by clicking on the following link:
From the drop-downs, select "Site and features" and then "Travel Map" (you'll see a dialogue box).
Your message will then be sent to the geography department.
This appears to be similar to a problem that occurred last November where a number of major cities including New Orleans disappeared from TA.
If you look at Biloxi on the main site no map appears on the main page or restaurants listing page and from a restaurant listing map there are no others nearby in Biloxi.
I'd suggest including the URL of this thread in the dialogue box so that mymsman's comments will be seen by TA Staff.
As for Iraq and Qatar if you look at the grouping of countries on the TA forums home page http://www.tripadvisor.co.uk/ForumHome you will see that TA has some additional groupings in addition to the traditional continents.
So Iraq, Qatar and other countries appear as Middle East rather than Asia. On the other hand the travel map awards badges based on continents but it appears that because of the Middle East classification they are not being counted towards Asia, Similarly Panama does not count as South America.
