No ads in the Chatbox (not a feature), but I'm not sure if that would work if it was an option. In such a small space, an ad in-between every 10 - 15 posts for example would probably get extremely frustrating.
Thanks for the feedback, @SpeedsterX . Obviously the best for the site is what most people want, so if it's overwhelmingly Chatbox in the votes, I'll put the time in getting it figured out with the developer if they're available & I can't get it figured out on my own.
But if it's close in voting, I'll most likely go with the megathread option. Outside of the few extra dollars (literally) it may add a month, there's also a better chance of that content getting found in Google and new visitors coming to the site.
Thanks again!
