looking ot implement a small sidebar chat/shoutbox on a site and don't want to go with an external solution and neither with a full blown chat. I need a solution for the sidebar.
your plugin looks perfect.
still, how is it structured? are all shoutbox entries normal comments to a certain post/page? That is how wp wall works. If that is true, I wouldn't need akismet as I have other anti spam mechanisms in place that protect my normal comments... and if it were structured like that it would be open for changes, i.e. I could switch to another plugin if needed.
regarding the ajax-shoutbox/chat, how much load does it put on the server?
