Howdy tamu mail ntust
It seems like you're trying to communicate in a mix of languages!
I'm assuming "howdy" is a friendly greeting from Texas, "TAMU" is likely referring to Texas A&M University, and "mail" might be related to sending or receiving messages. As for "ntust", I'm not familiar with that term, but it could be a typo or a word from a different language.
If you meant to say something specific, please feel free to rephrase or provide more context, and I'll do my best to help!
