:warning: BORRADOR

Esta consulta proporcionaría los temas resueltos/no resueltos, la primera respuesta | primer respondedor | horas hasta la primera respuesta, así como la publicación de la solución | solucionador | horas hasta la solución (con parámetros de categoría y ‘tema creado desde’).

Si alguien quiere verificarlo, sería genial. :slight_smile: :+1:
