On the caller end, the Blue Wave Offline Mail Reader required. It is easy to set up and run, and text files of instructions are available, too. The Swamp is a friendly place and a real-name board, so rules about censorship just aren't required. Callers here generally understand the difference between uncensored speech and hurtful speech, so censorship just has not been an issue. There is only one unforgivable sin here, and that is to intentionally try to hurt another user.
Disagreement is fine, but personal attacks are unwelcome.
While free speech is a noble goal, this in no way means anyone has license to inflict pain on others. This sums it up rather well. We all were once like that, and in some ways, everyone is still like that. But if something persists, and you feel that something is being inflicted on you, tell the sysop. If there is a pattern, action will be taken.
