Some comments:

int atoi_me(const char *numstring)...

Better to use const type pointer, as you don't intend to modify string contents.

int main()
{
    char number[MAXSIZE]; // array of chars
    int num;

    printf("Please enter a number:\n");
    scanf("%s", number);     // enter a string, not a char
    num = atoi_me(number);   // pointer to char, not pointer to pointer
    printf("%d", num);
    return 0;
}
