Is there a way to view all my past posts in the forums?

Is there a way I can go back through all my posts in the forums? On my profile it only shows so many recent ones, and that's it.

I'd really like to find a thread I participated in, in which one of Aaron's "side-project" plugins was supposed to be made an official WPMU DEV plugin. It was one that let users register for a specific site on a Multisite network.... I have installed, but had hoped there'd be an officially supported, updated version by now.

As I recall the plan was to make an official one, but I'd like to go back and find that thread and find out. Would be a lot easier to just search my own posts than try to search the entire community.
