We have a problem with the email facility which allows members to contact each other via their CBF profiles.
Our host introduced new systems to make spamming/hacking very difficult, and this has resulted in the facility becoming a victim of it.
We are working on it, but in the mean time:
1. Don't think other members are ignoring you! They won't get your message, and it won't bounce back to let you know either.
2. I will add a temporary members only message section, where you can ask others to contact you and add your email address, if the person you are contacting hasn't got it already.
Being members only it should be fine, and I will remove the section once we have things sorted.
