So we have this site (moodle.org) that I set up for information, community support and discussions about Moodle, and we have a team of people responsible for maintaining it and all the other .org, .net and .com sites, the SITES team at Moodle HQ, numbering 8 people. This team has only officially existed since June 2013, before that these sites were maintained by whoever could spare a bit of time from Moodle coding.
It's very clear to me (and I hope to you) that our sites need a big update, both visually/functionally to bring it into the current decade and informationally to be able to answer everyone's questions better and to help the world understand what Moodle is. I personally cringe every time I need to look at the current moodle.org front page on any device.
The team has been working through the issues for a long time, over a year. MDLSITE-1862 and related issues. Many of them come from tracker issues and forum comments over the years. We can't asking for community votes on every little step along the way, the process would just take too long (and it's been incredibly long already). But please understand that we do argue and discuss every little thing with the community in mind, and we have planned all along to show a prototype to key people (facilitators etc) here before going live with it.
One of these little things is the problem of all our Moodle courses on this site being called, currently, a confusing mix of "courses" and "forums", when they are in fact neither. In one discussion we decided that standardising on calling them communities would be the best way to clean up the mess and make things easier for novices. Perhaps that makes it easier to see why this course (which I named originally as Using Moodle) will be better off named as Moodle in English. Our world is multilingual and we should be inclusive. I agree it may seem a little random as it has happened in advance of the new redesign but I feel very strongly that multilingual communities are the right direction for Moodle.
