The BOSS Linux team has started a brand new forum for users and developers at http://forums.bosslinux.in/
It has a fresh new interface, powered by phpBB. The old forum is still available under archives. Unlike the earlier setup where separate forums existed for developers and users, here both are combined under the same forum page as separate sub-sections.
Apart from the forum user can also get in touch with any of the support centres for BOSS Linux found here for support, theres also an irc-channel, for more details on it click here. You can also chat online with the BOSS Linux team members here.
The forums aren’t as active as those of some other distributions, but thats mostly because BOSS Linux is relatively new. You usually get responses within a day.
