For you to get karma all you need to do is to ensure that you always make useful post and also make important comments on post then you will be rewarded with a positive karma, then for you to add profile pics go to your profile then you will see something like modify profile, click on the modify profile then there will be a drop down list, from that list you tap on forum profile then a page will open with different options click on upload avatar then a option will appear, on that option click on choose file then you will be lead to you photo gallery where you can now choose the picture you want to use for your profile pics and finally for you to become a jr member you need at least 20 useful post, thank you very much.
