Really I no understand very much about GNU license and cooperation in Gnu project .
I no understand because more of the people no make any aportation to any project.
I am long time member in de XMPP confederation. This is Jabber server and really there I make any contribution no only money also software and also i look every day for other member.
In asterisk one GNU software all is different small people . Thanks you areski make big contribution and other USER IN THIS FORUM also give money.
But in this software GNU A2BILLING no any make nothing for the community this is make addons and make skins etc.
Why ask for one new costumer skin and any people ask 600 dolars for make.
Really we go to pay to one parson to make but no this money and really in next year this is 4 days more we go to DONATION FREE THE SKIN to a2billing for put in the repository
I think we need to look in cooperation for this software from ARESKI have one good future.
Thanks
