Hello,  welcome to the forum

The first thing that I will advise to you is you should learn how to read about the forum first.  Most specially read the general rules and other essential details about bitcointalk.  There are limit on posting daily since there is time interval between posts.  Do not spam just to boost your activity, make your contents to be relevant to the topic. If you could do this; create threads that you think will be useful for most of the forum members, make sure that the topics that you are creating is relevant to the section. There are set of rules for every sections,  it will be goos if you will read them.
You could receive your payments via your wallet addresses, but for now,  that will not be from bitcointalk, it will be from campaigns that you will be joining soon if you already acquired the position that are able to join campaigns. Portfolio is not required,  but if you do have,  it's better.
Goodluck!
