Hi

The forum is subscription now if you wanted to post or send/receive pms. There are two types:
Forum membership which is £10 pa & Society Membership which is £25 pa.
You can post with both types of membership but there are extra forums for the Society membership including 'Ask Heather', 'Ask Becky' and 'Rider Health'. I think that the blogs section is Society only although some members made the decision to keep their blogs open for all to read on one of the other forums (can't remember which though).
