NOOB needs help. Bounty programs with bitcoin talk???

Hi, go easy - im new to using forums.

Ive invested in the crypto world for a while now and know how to buy / use exchanges yarda yard yarda.

Recently ive stepped up my game and learnt / participated in ICO's and airdrops. Which has inevitably led me to bounty programs. In the bounty programs they ask you to do social media task etc (which most of you know), but then go on to talk about bitcointalk thread. At this point i cannot get my head around it.

1. Whats a signature / embedded code and whats it used for?
2. Stakes? what do they mean /do?
3. Jr member on bitcointalk? How do you become one??
4. Bug report - is this aimed at skilled people or can anyone learn?
5. weekly report?

Like ive said in the title im a NOOB when it comes to this and any help would be appreciated. Im guessing their are many people like me, who are clueless and need a little guidance. The real question is, can anyone participate in bounty programs or do you need a specific skill set?

Thanks for reading. (dont laugh to hard).
