What other content management system at the level of Concrete5 can you get a reply from the CEO on a forum post that you made? What other CMS system can you talk with the core development team and then see your ideas come out in the next release? What other CMS team will give you tips, tricks and sample code for a tweak that you need to make for an add-on they developed?
At Pixo not only have we found the Concrete5 content management system to be the best open source CMS we have found but we are also grateful for the team that has put it to together and continue to make it great. A big Thanks to the Concrete5 core team!
