Newbie here - How can i join bounty campaigns? what to do? Thanks!!!

There are actually a lot of earning opportunities here in the forum and that is just a bonus or perk of being here in this Bitcoin community. Since you are still a newbie I highly recommend you not to think of getting paid from campaigns or bounties first but you need to explore on how this forum works, it's rules and regulations and what is your purpose of being here.
During my newbie days I stick to my local board and ask there everything I need for clarifications before posting here in english boards. I actually created a thread in our local board helping newbies on how to apply, qualify, and get accepted in campaigns but unfortunately I think it was already locked due to hundreds of new threads are created day by day.
So If you are really interested on what you want here kindly do your own research for we are only here to guide newcomers not to spoonfeed.
