The main reasons for joining professional organisations are firstly to keep up to date about what is happening in the industry and then, a chance to influence the organisation's response or to stop other people influencing it in ways you don't like.
Every industry or profession is always undergoing changes both internally driven and in response to external forces.
If you care about your profession and its future then it is always advisable to become a member of whatever organisations there are.
The primary benefit is that you can keep yourself informed about what is going on.
How involved you then get is upto you.
I'm pretty sure almost any organisation would be wary of any unknown suddenly announcing a desire to take part. For the most part the influential and active members are well known and respected in the industry and often co-opted or invited to take up positions on committees and working groups. It is often a lot of work with no recompense. Many members are active members because their companies will pay their fees, pay for them to attend conferences or pay for them to spend time working on various projects for the organisation. Why? because there are sound commercial reasons for wanting to be influential in such organisations.
Sure, there is a need to maintain professional standards but don't forget the commercial imperatives. In the end it is about how easy it is to operate in an industry. Professional bodies influence this.
Professional organisations like to organise events, conferences and social events at which you can network and to publish periodicals in which they sell advertising.
It provides you with a platform to make your views known and to let other people assess you and get to know you.
The first thing such organisations need are members who will pay a subscription and
receive information, newsletters, announcements and so on.
You need to do become a known factor. They need to size you up before letting you loose in committees and working groups.
Offers of participation can be regarded with suspicion if they come out of the blue from unknown entities. No-one ever really wants to do things without some ulterior motive. The most easily understood motives are commercial or private advantage.
The couple of organisations I belong to I mainly receive information, it is how I keep in touch with what is happening and what activity there is that might affect me. But because I have contributed articles/advertorials to their publications and because I have earned, I guess, a certain credibility, I have also been invited to give papers at various conferences.
Most recently I have been able to initiate a working group to look into a particular aspect of the industry.
Naturally I have commercial interests and interests in influencing how the industry responds. I'd like to see certain outcomes but what I expect is that the outcome will be a compromise between the various interested parties getting together and working out a solution. It may or may not then deliver a benefit to me commercially.
What I take care to do and, I'm sure, what the organisation takes care to ensure, is that private commercial/personal interests are aligned with the interests of the organisation and industry as a whole, that those interests serve the industry and do not try to wag the dog.
An enquiry for membership would be treated with open arms... here's a form, fill it out and send us your cheque. Once we get to know you you may be invited to join certain groups.
A sudden desire to "do good" will arouse suspicion. An out of the blue offer to do some sort of voluntary work would, I suggest, raise some eyebrows.
