Is the following paragraph acceptable? Please check it for me. Thanks!

Actually, a magazine which is scheduled to be issued this month had already been done two or three months ahead. If there is breaking news that is urgent to make the readers know about it, the editorial staff will use the latest event instead of one of the previous articles. And, so do the CD-ROMs. It takes tremendous collective efforts and costs a big amount to finish publishing a magazine or making a CD-ROM.
