It's in Euro not in $ - Sorry for that...

@dimalifragis Yeah I figured that out. thank you
Step 2
Step 2
you are accessing wordpress.com - that is the wrong website. You want to access wordpress.org.
This is the wordpress.org page for wpForo, which others confirmed is free
https://wordpress.org/plugins/wpforo/
@fawp Ok thanks.
wpForo costs nothing, only the addons cost something
You can download wpForo here = https://wordpress.org/plugins/wpforo/
but you need a self hosted wordpress or a WordPress.com account
180€ costs the WordPress.com Pro Account per year, if you want to have it

@tutrix Thanx
Probably no longer relevant to your question BUT I think useful for you anyway. You can always test on a localhost on your desktop/laptop. That way you can totally test apps like WordPress and free editions of plugins (from e.g. wordpress.org, keep in mind premium/pro editions of plugins will always cost money) for free. This way you won't need to have a webhosting package available just yet, and it is always handy to have in place while developing your site.
Perhaps the easiest solution for you -when this is all new to you- would be localwp.com but there are plenty others out there: MAMP, XAMPP, Laragon (my personal favorite but it needs an massive update of the packages so I've completely updated and patched my installation manually), etc...
