I tried to become member of my local one and they never replied to my application for membership.

Have you checked if they have an open day? Many have a dedicated public day every week where you can just drop by and if you are interested someone will probably happily assist you with becoming a member.

Otherwise joining their IRC and asking there could also be an option.

Try showing up physically on their open evenings, which most spaces have.
