PISE follows the tiered approach (which is the default for any student organization in the Netherlands). There, the board is involved with strategy and day-to-day operations, active members are part of one of the organizing committees that focus on careers/socials/marketing or some other topic, and passive members just join events.
However, I can definitely relate to the inclusive vs exclusive issue. When we first had low barriers to entry, some people became active members without reading up too much about EA. Later in the year, conversations were sometimes diluted when some participants had no more EA knowledge than the basics. On the other hand, some of the members that showed the greatest progress over the year, would not have been accepted to PISE in the first place if there had been a higher barrier to entry.
Could this also be a good opportunity for pages written in languages other than English?
