there is no such activity going on right ATM. We are busy setting up the needed bits for opening a donation page. See my post a few above.
Factoid that might interest you: we are not going to use any of the popular crowdfunding sites. The donation page will get announced on neo900.org and here, as soon as it opens. ETA right now: still next monday.
We just evaluate every single statement/value/number we will publish, so we won't disappoint you by not keeping our "promises" (e.g. we reduced "promised" RAM to 512MB since it's still unclear if we can get 1GB, though we will strive hard for 1GB nevertheless), and that takes some time, as does the evaluation of the legal implications (tax etc) and other related stuff. Setting up timelines is a further topic we're busy with.

So stay tuned. RSN!

PS: btw we already have a newletter you can register for on neo900.org, and afaik also a RSS feed.
