I am really stuggling with these changes.
I don't think there is a favorites list anymore. sigh. I know what you mean, I hate having to look up each board in between.
i know if you click on your name under your avatar it pulls up your last posts that you have made. so you can use that to jump between boards. i am not sure if they are adding that feature back or not. i know a lot of people are missing that part.
