[xwiki-devs] about proposals

Hi, From time to time, I see developers sending proposals to this list. Of course I'm not a developer, but I would like to know what is a best channel to propose some changes that I find useful for XE/XEM or other applications. What is it better and/or advisable: to create a Jira Issue or to send a message to this or users list? Thanks! Best, Ricardo -- Ricardo Rodríguez CTO eBioTIC.
