The WordPress Glasgow meetup is one of 24 WordPress monthly meetups currently active in the UK.
If you can’t make any of the monthly meetups, some cities also have yearly weekend events called WordCamps. You can check out the closest to you from the WordCamp Central website.

As you probably know, WordPress is an Open Source software and, therefore, is built and maintained completely by volunteers from all over the world, and not just by developers!
If you are interested in finding out more or getting involved and helping make WordPress even better, there are many ways you can get help. In the Make WordPress page you can find all the teams and an explanation of what they do.
