Omg!!! I've been looking for 30 minutes now, and I just can't seem to find any way to download ProfessionBuddy, so I can get Mining + Engineering-bot running-
Um.... did you look in the forum that you posted in before you posted? I literally show your post directly above this one: http://www.thebuddyforum.com/honorbuddy-forum/plugins/free/32628-profession-buddy.html
which lets you know that a fresh install of HB should allow you to use PB if you can't already see it in your Plugins list. (aka, it is part of the HB download, you don't need to install it seperately).
