Members

There are different level of membership that you can have within the party. Some of the structure is from following Texas state election law and some is from the Libertarian party rules. 

Participating Member

This really isn't a level so much as just recognition that you want to be involved in the party at some level. This could be just coming to meetings or events.  Also it could be more like donating money or time into spreading the ideas about Libertarianism. Some may want to support a particular candidate but maybe do not consider themselves part of the party. Whatever the involvement level there is always room for people that are interested.

Voting Member (Affiliated)

This membership level requires that you affiliated with the Libertarian party officially and support its principles. This is usually done at a convention according to state and party rules. Member at this level can vote on party matters and can be considered for becoming a delegate at the conventions. It is strongly encourages that members of this level also donate, but there is no current requirement to do so.

This level allow for much more say in how the party functions and the direction it takes. Affiliated members help decide who their candidates will be and they party representatives. You can read more information on how this works on the convention information page.
