I find this hard to understand.
EVERY other forum I am a part of, from small 100 member forums, to large 50k+ member forums, uses it.
The ads that you speak of don't pop up on the website, only on the tapatalk app.....on my end, not on yours. It will not affect the appearance of the forum on the web or anything like that, nor will it interfere with your advertisers.........
It's free. Could you give it a shot and see how you like it?
The benefit is, lots of people don't get to spend time sitting in front of a computer to browse a forum, however, they can spend the time on their phone. While using the bathroom, sitting in waiting room at the doctor, etc......offering them more opportunities to spend time on the forum.
Just my $0.02 of course.
