Thank you for your recommendation on Version Control tools first. Now we choose the CVS because of its easyliy to use and plenty of documents. And it's enough for our system.
What bug tracking system do you recommend me to use? If you can tell me why the tools you recommend is better than others is better. Both the free ware and commecial ware is ok. We have embeded software team , application software team,
testing team and others, so we need to work together on this system. I've used the ClearDDT, when I need to call the IT assist to repair my PC I write a CR to him. I think this feature is great.
Thanks in advance.
