SueBaroo - broadly you are right, and I think the OG moderators are very good at "cleaning up mess" - locking duplicate threads with pointers to the existing one, merging where necessary, stepping into heated arguments to remind people of the Code of Conduct and so on. That's not to say that certain mods don't have agendas, though - they are human and are not always totally impartial.
One thing I don't like about OG, especially in the Tenth Planet - and I'll be interested to know if you and serenity pick up on this too - is that there is sometimes quite a bit of parent-bashing and sneering at kids. (And if you thought our Madeleine McCann threads were hostile, people, you should see theirs!!) People are not always hauled up for it, whereas they are for the slightest hint of an "agenda" against other groups.
For various reasons, parents are in the minority on OG and I sometimes have to bite my virtual tongue and remind myself that I am arguing with someone who hasn't grown up yet, and is in fact nearer to their own childhood than to where I am.
