Can I say first that this is not a major problem, more of a minor irritant.
I like to be able to hide threads I'm not interested in - this tends to be the quiche threads etc Why can I not hide the stickies at the top of chat? At the moment, there is one about London meet-ups. I live nowhere near London, I will not, and never will go to any London meet ups, yet I can't hide the thread.
Like I said, not the end of the world, but I'd really like to hide them please.
