My son received a student email in his tamu.edu Inbox saying that his time slot was activated yesterday morning.
The email instructions were a little confusing, so I will share some tips.
The email says go back to the (housing) application. You need to go back to the tamug.edu website where it says “Apply Here” (for housing). Google to find the TAMU Galveston housing application website again. Click on Apply Here (even though you have already applied and presumably have your room selection timeslot). The next page has the tabs that the original timeslot assignment email referred to. Click on the “Application” tab at the top of the page. Because my son was already signed into Howdy in a mistaken notion that he needed to access housing there, there was no separate login to this reslife.tamug.edu website. They already knew who was accessing the application through login carryover. I am sure they would prompt you for login otherwise…
Note that there is an informative video on how to use the website to pick a room with any confirmed roommates, etc. right after you click on the Application tab.
My son had no room selection ability on this website because freshman Corps have assigned rooms (they can pick a roommate, however). That step was just not available.
