Using the computer

Today I talk about using computer. I think using computeris very useful. But I think that a pit is in the convenience of the computer. For example, BBS. BBS is Bulletin Bords System. It is Keijiban in Japanese. Anyone can easily write in the BBS.But it is cause about trouble. Bullying in the BBS becomes the serious social problem. I always use computer. Because I did homework at KGU. But I cant understand computer. My computer is windows 8. Thats why, I lost how to use computer more and more.
