I've just signed-up for Lucee Membership, at "Supporter" level (this is the lowly US$9/month option... that's six quid / €8). I currently don't have anything to show for it except for a receipt, so that's not very exciting.
But I do feel good that I'm putting my money where my mouth is, and am supporting the project. So if you're a former-Railo / new-Lucee community member... get on board. If an unpaid blogger can pony up $9/month, so can people who actually used the product to earn their living! I also think it's really good that our language / platform has an association, so we can work together to make it better.
