I had YAF up and running fine on my dev machine. I was messing around trying to integrate with an existing site and modified a bunch of data in the YAF database.

So now, I simply want to recreate the YAF database. I've made a lot of changes to the source code, so I don't want to reinstall everything, just the database.

Is there a way I can do that easily?

Work fine for me.

I don't need to synch a dev db with a production db, I simply need to recreate the YAF database from scratch. I suppose I can run the install again, but I just need the db, not the entire project.

I figured it out.

All I had to do was delete the database, recreate an empty one and run the forum app. The rest was taken care of for me.
