I have sent an email to everyone on the forum who has signed up to receive emails. I'll also send out a newsletter to the Spirit of Cardiff mailing list later on.
If you do email other people about this, please be sure to only email friends and other people who you know are willing to accept email from you.
know it's a good cause, and it's important to get things moving, however if someone receives an unsolicited email and decides that it is spam then it will mean trouble for rib.net and spirit-of-cardiff.com
For more information about why spam is bad (however well meaning!) have a look at some of these sites
