Where Are the Rules for This Site ?

This is a part of the attraction of this forum. There are not very many 'rules'.

However, the community does seem to enjoy civility and decorum, and we sort of police ourselves. Occasionally someone needs a nudge back towards a decorum or civility aspect, and a moderator will intervene and provide the gentle guidance required. There is very little tolerance for shouting/pouting/whining/bickering/bigotry. Likewise, there are a lot of places on the internet to discuss politics and religion, so you do not see much of those around here either.

There does seem to be one hard and fast rule, found within your link:

The owners and administrators of CR4 reserve the right to remove, edit, move or close any post or ban any user for any reason.

Retribution can be swift and sure. Play nice, and have fun. Sign up and join our little community.

I see thanks for explanation
