Thanks, opentype.
In our community, I'm fairly sure that most users don't look at the activity streams, even if I did add a link there. You know how most users are, they're in a hurry, they want to find what they need very quickly without having to think.
Maybe I should create a custom stream made from content the user either started or posted in, and create the button myself?
As a user, that's where I would expect to see it. I mean I can access my profile, my attachments (which I never need to access in my case), it would make sense to me that I could access my posts from that same menu.
