Whether you’re a developer, administrator, architect, or business user, the Liferay ecosystem is massive, and one way of getting involved, learn, and contribute is through Liferay User Groups (LUGs).
A quick clarification: when we talk about Liferay User Groups on this post, we’re referring to the geographic, in-person, or virtual gatherings of Liferay enthusiasts, not the “User Group” feature for managing permissions within Liferay.
How to Join a Liferay User Group
Liferay uses Meetup as the central hub to manage and promote our official user groups globally. To find a LUG near you and see their upcoming events, simply visit the Meetup page:
