Welcome to The Cave of Dragonflies forums, where the smallest bugs live alongside the strongest dragons.
Guests are not able to post messages or even read certain areas of the forums. Now, that's boring, don't you think? Registration, on the other hand, is simple, completely free of charge, and does not require you to give out any personal information at all. As soon as you register, you can take part in some of the happy fun things at the forums such as posting messages, voting in polls, sending private messages to people and being told that this is where we drink tea and eat cod.
Of course I'm not forcing you to do anything if you don't want to, but seriously, what have you got to lose? Five seconds of your life?
To answer the quesiton... Cause the admin said so?
Luckily I don't think that's really been a problem in the coughing cupboard. Most trolls are just trying to generate a response, not be flat out jerks. if it's a problem by all means change it, but I don't really see a need for that at this point.
Nor did I, as it happens.
I think the deleting happened fast?
I don't exactly know what was going on, it happened before I had logged in and I heard that stuff had been said that was horrible and it was deleted.
And as superbird said, a five minute process won't stop a troll, as they would have to do that anyway to troll the CC threads.
