I own a couple of xenforo licenses at this point, but when I start up a new site I don't always have the option to pursue a premium solution for forum software. Generally, my approach is that I let the site built up for a bit, and once I see it getting busy I do a quick conversion over to my forum software of choice (which is obviously xenforo). I was curious about the opinion folks here have on what free forum software they would prefer to run on their site when/if they can't purchase a xenforo license right away. I tried to think of all the options I have heard of and added them as voting options. I'm sure I overlooked some, so if you pick 'other' then let us know what you use, please.
