I'm not sure what else you'd need for now, so let's get started with clubs! :D
So I see you haven't posted in any clubs yet; I think it's time we change that! :D First off, it's important to choose a club about something you're really interested in, otherwise its hard to keep interested and keep posting in them. For your first club, I suggest you join one based on your favourite Pokemon type. You can find a list of all the currently active clubs by clicking here, so choose one you like and take a look at it. c:
The most important part of any club is the first post of the club. The first post contains a list of the club's members, information about the club, rules, sign-up forms, and often trivia or challenges to take part in too. For example, take a look here at the Poison type club's first post to see what I mean.
Before you join any club, it's important that you take a look at the sign-up form. This is always found in the first post of the club, and you're advised to post it in the thread before posting in a club. Have a look at some people's first club posts here, here, here and here to get a feel of what I mean. Another important part of clubs is that they always have a 'Current Topic', which is what the discussion at the time is focused around. Some clubs change this topic once a day, some will change it a lot less frequently, but it's important to try and answer the topics when they're given and keep discussions related to them - although as long as you keep all of your posts about Pokemon then a little off topic stuff is okay. :3
So hopefully that should be enough information to get you started in Pokemon Clubs - we can tackle some other sections when you're comfortable with this one. ^^ If you're at all interested in owning and running your own club, then make sure you tell me and I'll take you through the whole process of club creation and ownership.
Also of course if you have any questions about anything else in the forum, feel free to ask! Stuff like making signatures, VMs/PMs, the infraction system, emblems; all this kind of stuff can be confusing at first so make sure you give me a shout if you need help at all. ^^
