The trouble is, if it were me running the forum I'd tell those complaining to sort their heads out and take the person who made the comment to court and stop being so silly.
It's a simple rule, don't mention personal names or companies, if people stuck to that then fair enough. Talk about a possible problem but no names no pack drill, got real bother? ring nominet up.
Admin does good on here, it's a nice helpful and friendly environment with no hatred and it needs to stay that way, don't slaughter or slag others and I think all will be happy with open debate but no names no pack drill, got bother? ring up nominet.
No, they don't need their own forum and if they did that's for them to decide, I don't think acorn needs any traffic taking away from it and nominet bods in individual capacity seem happy enough posting amongst friend and foe.
