Washing off semen

Q: After ejaculation, what do I do to my clothes if it had got soiled? After my clothes got soiled, I washed it with the rest of the family's clothes. What should I do. Is the ibaadah of my entire family unfulfilled? Do I have to rinse my dirty clothes before putting it into the washing? If my bed got soiled with semen but I did not clean it, will I be napaak everyday?

Free software for students

Q: One company gives software free for students. Those students who have university email addresses can apply for this free software. I am a student but my university doesn't provide us with an email address. If I download this software and crack it for my use as a student, then is it a sin? They provide free for all students, if I don't have a university email still I am a student.
