I am new to open source world and not familiar with open source license. So I need your help.
My company is a web site, we need a support team to answer questions of customers and wan to use openfire server and spark client.
If I want to use openfire + fastpath + spark + webchat in my company (not for sale), is there any legal issues?
If I want to modified some sources of openfire or fastpath or spark or webchat and use them in my company(not for sale), is there any legal issues?
