*update*
We saw quite some reaction to my previous post in the shoutbox, so let me add some more thought here.
Now, lets assume you just realized the "union members"-problematic as outlined above does apply to you, but you really just realized there is a problem here and now you are wondering what to do with the tracks you have already posted to wikiloops.
Let's take a deep breath and think this thru:
First of all, there is no need to panic, since you have not received any email from my end telling you we were facing a legal claim by your union - it may happen any day, but it has not happened so far.
What you can do to prevent that is to remove all your tracks, right?
Now that would be quite a dramatic solution to the problem, but may seem the solution at hand.
If you know the wikiloops rules a little, you will know that you may delete any upload of yours without problems under the one condition that no one else has posted a remix of that song.
So far, so good. But what about all the remixed tunes?
If they were to be deleted (yours), all tracks involving your track (the remixes of your tracks) will have to be deleted as well, because you are part of them, and the remix-branches would be broken once we remove a track that has a remix attached.
That means, someone will have to inform these remixers about this whole situation and explain to them why we have to remove their precious tracks.
Needless to say, that is not a nice job to do, and not a nice user experience for the people who took the effort to create those remixes.
I hate to say it, but with this scenario in mind, I feel it is necessary to point out who is to blame for this mess...
Both wikiloops and the remixing users are not to blame, since everyone relied on your statement when stating "I am the only one holding rights on this, and I'm granting you the right to go ahead and create remixes" - the first half of which just turned out to be plain wrong, at the price of causing me a week of work to clean up the mess (I had to do it before) and frustrating X other wikiloops users who see their tracks removed.
That's not good, to say the least, and -as you will understand- that would end in your account being closed and further registration being blocked.
The only other option we have is to make a straightforeward deal with your union to allow what you have been doing, while the question remains what the cost of negotiating such a deal might be and who would pay that annual fee... you know the budget situation of this project, right?
There may be other ways to solve this in a rather shady way which I will not add here in this public scenario, and which I do not feel good about anyways.
The damage is done I'm affraid...
All one can say in conclusion is that it would be nice if people would read all this as a strong reminder to act responsibly,
a case like this one blowing up in a legal case involving international lawyers would be enough to ruin the wikiloops project financially.
You wouldn't want to be the one who is responsible for that I guess.
If you find yourself at the end of this post thinking "shizzle, what do I do now?", I recommend getting in touch with me by PM.
As you may be able to tell by my words I'll do my best to act reasonably, even tho the scenario is not an easy one to carry once you are aware of the possible endings.
Mistakes happen, let's do our best to find a good solution.
