New Post: GetUserFromScreenName returning null

Thanks for your response.

I suspected that I was hitting a limit somehow. I looked for a GetUsersFromScreenNames function but could not find it. Another issue with GetUserFromId or GetUsersFromIds is that they take parameters of type int, but there are user ids that are higher than the maximum value for an int (the first user id I looked up in fact).

So, a GetUsersFromScreenNames function would work for me otherwise GetUsersFromIds would have to be modified to take a BigInteger (or maybe just a string).
