I realy like your ideas about the donations account I think it would be a good development for earthcoin. Of course such things should be completely transparant on the site to give trust. In the beginning of eac there was a premine (for the development of EAC if I remember correctly) there was so much discussion about that. It never became clear where it has gone,  probably sold.
As for the change in algo are there any risks or cons and how does the change go into work can you give more insight in doing that, should every eac miner stop mining script with the old client at once or can the different algo's run next to each other for a while?

And a hurray for myself I compiled earthcoind.exe
