Paid Community Intro

You run a paid knowledge community and need an intro that makes the right people pay to join. Based on the info below, write the intro.
Requirements:
1. cover a one-line positioning, who it fits, who it does not fit, what you keep providing, update frequency, and FAQ;
2. be clear about who it does not fit, and only promise an update pace you can actually keep;
3. never promise earnings, contacts or resources; never fabricate member counts or renewal data; avoid superlatives;
4. if platform features like free trials or referral rates are unclear, mark them as placeholders to confirm with me.
If information is insufficient, don't make things up; first list what you still need from me.
Output format: the intro in sections, ending with a 50-character short version for external promotion.
