Yes and no.
This is almost too trivial, but it's also easy to forget, to overlook, to cause some silly confusion. It's worth some chat.
The "signing up" into the website creates or confirms your profile here. You provide your contact information and set your email preferences. The site automatically tags you as site member. Anybody can do this at anytime and at no cost. However, it does not make you a club member.
To join as club member, go to the Join webpage.

Once you become a club member, you get a welcome package that shows a lot more resources, of which this site is only a subset. Club members are encouraged to sign into the site here to confirm their contact information. Pick a password. It's best to sign in as both site member and club member. Then, whenever you log in, which is possible only if you're a site member, you can post or respond to posts in the Forum section as a club member. You'll then also see a club-members-only section. It gives you access to discussion not shared with the general public.
Although we're primarily a speaking club, the practice of writing helps organize our thoughts.
