GoFuckYourself.com - Adult Webmaster Forum - chat logs does this exists?

Basically I am looking for something that's like blog, or chat log on an instant messenger, but for it to be online.

Blog for example is ok, but I am looking for where

3-4 people would talk on one conversation

Let's assume 1 of them, isn't technically advanced, I mean really isn't, so no software downloads, just works right from the beginning.

Continuous chat log
where each person posts maybe only one time per day

so the chat could go on for 30 days
with each person responding 1 time or 1 time every other day, but the entire chat log is their for each to view?

Is there anything like this?

If software downloads are needed, passwords are needed, or you need to sign up to an account like a bbs, etc this concept won't work.

There should be a unique link for each group so that one group doesn't see the other groups conversation as it wouldn't be relevant anyways.
