I've been tidying the forum up a little as I realise its getting rather... long, especially for the GM's. Here's what we can do;
1. Leave them, this means all old events will be available for all to see.
2. Create an open "archives" user group that anyone can join in order to revisit those forums, but otherwise have them hidden.
3. Hide them from all.
No, I am not deleting them.
