I?m developing site for a client based on joomla and community builder. I?ll be paid money (hopefully) however I want to make sure that what I do is legal. Joomla and community builder are developed under GNU GPL and so my question is if I can charge money for what I do. I also want to remove Joomla ?powered by joomla? and this annoying ?about community builder? option from CB profile menu. Furthermore I need to put probably at the bottom of the screen information saying ?developed and maintained by heregoesmyname?. However all the internal comments (php and all server side stuff) and copyrights will stay the same, as I said with exception of those in html files which are getting downloaded into clients computer. Is it ok or am I breaking some laws? Thank you in advance for your help.
