Thanks for bringing that up, googley!
Whether or not any moderators appear to be online at the time, one of the most helpful things you can do is to save a transcript of the chat. PM a copy to any
moderator or administrator with your comments. We'll discuss it and decide what action to take, if any.
Here's something I wrote almost a year ago about saving chat transcripts. I rarely chat so if anything's changed in the meantime, I might very easily have missed it:
When you're in chat, between the big chat box with everyone's replies and the smaller one that you type your replies into, there's a row of controls starting with B, I and U. The icon farthest to the right looks like a sheet of paper with a floppy diskette on it. Clicking on it should open a new little window with the chat transcript in it. The times I've saved transcripts I've highlighted everything, copied and pasted to a PM or a document file. If anyone figures out a better way, please let me know.
