I don't know what RTK is but I'm surprised they teach you 吾 at all. You will only see it in old literature. Don't worry about it.

What you should worry about is the use of どうもありがとうございます in your post. You only say it when you have received a service (in this case, an answer), not before. Say よろしくお願いします.
