Martin, David's suggestion is essential, so please put that together quickly, but PLEASE, David and everyone willing to contribute, in whatever amount they are capable of, be explicit about the amount you intend to donate. Saying, "I will contribute something" is not helpful. We need real numbers, and we need them quickly. Airfare is going to be the major cost, and the longer that purchase is delayed, the more expensive it will be. We are talking about $1,000++, so please keep in mind who you are doing this for when you pledge your contribution. Also keep in mind that Martin's Warpstock presentation is crucial to the survival of OS/2, and that can't be overstated.
Also, in advance, let's stay on topic in this thread. If you have something to say other then the amount of your donation, possibly including a brief positive and encouraging statement, start a new thread. What is needed in this thread is NUMBERS, pure and simple.
One last thing. Everyone of you knows another OS/2 user that also benefits, and if they understand the full scope of what Martin has done and continues to do, then it's appropriate to say that they benefit greatly every time their OS/2 desktop boots up. Email them and ask them to read this thread from the beginning. That is something that every one of you can take a couple minutes to do as a gesture of good will. It matters, so please, don't think about it, do it.
