I don't know Olivia at all, but wish her well if she is suffering from MS and desperate to try a treatment that gave her relief before, even if not permanent. I also didn't know Tamn when he was ill and a fund raising drive on the forum got started to help pay for his treatment, but that seemed to work out ok, even though it also had a lot of controversy going around it.
All of this struck a chord very strongly with me personally, as someone who once upon a time attempted to do a series of ingame events that raised funds for real life charities. I had hoped at some point in future to pick that up again, but things within EU haven't been right for that for me yet, so maybe in future. I did those few events on CND with the help and sponsorship of ND (who already had a Save Reality Go Virtual fund in place back then, with a portion of CND taxes going to an animal charity) and many others, and we raised a decent donation for several charities in the process before I had to leave EU for personal reasons and could not carry on with the events. Understandably some were always skeptical and I did the best I could to show receipts and evidence of the donations etc, we even got a certificate of appreciation to the 'Players of Entropia Universe' from the cancer charity we supported with an event. Whatever is going on now with ND's reputation, doing this kind of thing then is not new for him for what it's worth.
However, I instinctively knew that while giving to charities would raise some controversy, and some skepticism, to have attempted to do this for an individual would have been far rockier ground, and I was not and I don't think ever would be brave enough to take that on like ND has in this case, as it would have meant exposing a lot of that person's life in order to provide 'proof' of the illness, proof of where the money was going etc. I'm not judging in any way any of this situation either, just saying I wouldn't have done this myself in my charitable fund raising efforts, as it did have a lot of open doors to be questioned reasonably.
Interestingly, at the exact same time I was doing those events, including one for cancer research, I myself was ill and finally diagnosed with a supposedly terminal case of cancer. The thought of somehow using my events or my ingame 'contacts' to raise money for my treatment never crossed my mind, instead, I sold out, left and in the end also chose a radical and unusual treatment to try to stay alive. It cost me everything, but it worked, and in that sense I don't regret basically having to start my life all over again with nothing to show for all the years of work before that.
Sorry to ramble off this way, as I said this whole subject struck a chord on a very personal level. Clearly the potential has always been there for folks playing in a RCE to do beneficial things for the real world and real people, and I hope to see more of that, just hope something can be designed that will leave such efforts less open to worries about legitimacy. In that regard, what struck me the most in all of this at the moment is the information that MindArk itself is willing to be involved and hold an escrow account for this 'event'. They didn't do anything like that back when my 'Save Reality' events were around, which is a shame, would have helped a lot of the sceptics I suspect? I know MA later offered to occasionally sponsor some events if a promoter convinced them to help out, like WoF for example, but this is something much more complicated, and frankly I'm surprised they agreed to get involved that way, as it is a lot of extra work for one or more employees at an already difficult time, and it sets a precedent as what grounds would they have now for denying the same service to myself or anyone else in future doing RL charitable events?
Anyway, best of luck to Olivia in getting better, and well done to ND for trying to help, nothing more one can say really without knowing more intimate details.
(regardless of some peoples opinion), you can choose to partcipate or not...the choice is yours. Still in awe of how some are flaming this thread and someone in real need to basically survive.
