The simplest thing to do is to use the Moodle feature that is there for exactly that purpose.
Thanks a lot guys, I'm sure that will help quite a few people who can't upgrade to 2.x for whatever reason.
Nope, not yet. I'm still drawing a normal salary and paying off large mortgages in my home town of Perth (one of the most expensive cities in the world).
However, because of support from the community and Moodle Partners, my company is able to directly fund around 20 people to work on Moodle full-time and that is a beautiful thing that I am proud of.
You are absolutely right, Glenys! ... I thought I was seeing things there's definitely a bug there. It seems to be related to people CHANGING their rating - the re-calculation or saving is not quite right. I've filed MDLSITE-1753 for it in the tracker for the guys here to look at.
Ha, funny analogy.
As for your other question, no, Moodle Partners are not required to contribute to Moodle in any other way than by their 10% royalty payments. However, the bigger partners all do additionally contribute to the code in some way (either by coding, or bug fixing, or specification development, etc), because they want to be (and also to be seen to be) a true part of the open source community. It's about respect.
Likewise, their clients often have particular concerns (eg bugs) that need addressing, and we (Moodle HQ) prioritises those concerns. It's a very symbiotic relationship of goodwill and co-operation. And everybody in the world gets to use the resulting software for free. Win-win-win.
