Hi, thanks for ur answer. but my question is, is there any thing in alfresco's environment as bug tracker? I don't want to import the alfresco's bugs. i want my customers, who has my product, could be able to post my program's bug in alfresco!
I don't know of any bug trackers implemented on top of Alfresco, but it'd be worth checking the forge (http://forge.alfresco.com/) to see if someone in the community has implemented and shared one.
