Browsing the forum without being “signed up” triggers a quite annoying invitation, with an option, called “no thanks”, that only delays the next appearance of it very briefly.
This might not be under control of the moderators and is not important.
I passionately hate nagging of any kind and usually don’t revisit sites that use such messages, but I understand that most people are not like me because they prefer to be wrong and these messages actually work for boosting sign-ups.
Although I’d bet that nagging/nudging doesn’t work on everyone and it possibly creates an “engagement-aversion split” (or “nudge-reject dynamic”) of sorts, where some types of people are more likely to sign up, while others get turned off and never visit again precisely because of the nagging. It’s very likely more complicated than welcome templates simply boosting sign-ups is what I’m trying to say, but they do when just looking at the raw numbers AFAIK.
Then again, I’d say the boat is full and we simply shouldn’t welcome new users anyway. I mean, if someone isn’t into photography by now, it’s obviously too late and it’s just not for them anyway. I’d propose a non-dismissable message that prevents people from guest-browsing the forum at all. Good thing I’m not an admin.
Learn something new every day. I was sure it could be configured.
It should be possible to prevent the message from being displayed in the theme settings CSS. But again, these message drive sign-ups, so that wouldn’t be a good idea.
If it bugs people that much, use something like ublock origin to his the element. You’ll never see it again.
Also we don’t really try to “drive signups” at all. We don’t really make money from this nor try to monitize outside of the donations button, so more signups isn’t really better for us.
