Prata How would I get more users onto the forum without being spammy or invasive?
We try to be public everywhere. To do this, we use our RSS feed and post on our Facebook page with #hashtags. This means that a lot of people come to our Flarum. We do the same on Telegram. If you are not interested, you don't subscribe. So it is not spam ;-) However, if you search for our forum-related words, you will find us. Whether on social media or Google.
Otherwise, it is important to create topics that can be discussed.
As a result, we have almost 2000 users within 1 year. Around 700 are active.
