This week Meetup.com announced that it is going to charge event attendees a mandatory $2 fee to attend events, even if those events are free. Meetup.com is commonly used for local gatherings in the tech industry, including the WordPress community.
This change will not affect members of the WordPress Meetup chapter, according to Andrea Middleton. Andrea notes that if a WordPress meetup group isn’t in the WordPress chapter and wants to know more about joining, they should check out this page.
The Meetup.com page linked above is being updated periodically. They could be considering the negative backlash on this move, and there may be future updates to follow there.
