I am still new in MSE,and still learning how to use MSE properly. Sorry in advance.
MSE has really nice Elementary number theory questions and so many nice elementary diophantine equation , and since I am learning Number theory , I want to solve more questions , specifically diophantine equations, but searching them is hard on MSE , cause there a lot!!
So will it be appropriate to post a question on MSE , asking for "nice and beautiful diophantine questions and links one has solved and would recommend a Olympiad number theory student to try " or something like that ? I mean there a lot of experts on MSE , who will be very happy to share their favourite questions.
