Playing Nicely

Can I make a request that comments relating to Plan B remain polite, and factual? I don't want to act as a censor, but I will if I have to.
There have been a couple of comments that have gone beyond what is reasonable, and I don't want anyone else to be upset.
Both Leon Morelli and Gareth Ratcliffe have spoken to me privately about this.

I started this blog to be fairly cheerful and light hearted about what's happening in Hay - I don't want it spoiled by a few people posting anonymous comments.
Thanks.
