Well, mostly it's the knowledge.
Basically anything what happend since BTC bang has some sort of record here. First faucet, first purchase (famous 10k BTC pizzas), BTC hack in 2010...
Some users are making guidelines to help newbies with their initial struggles in cryptospace.
In
Marketplace section you can purchase/sell goods or offer your own service.
You can also ask other users for support in case of doubt whether some service is legit (myself helped couple users to avoid being scammed by fishy online shops).
In
Meta section you'll find rules and info related to forum.
If you're tech-savvy I'm sure you'll find interesting
Development & Technical Discussion section.
... I also get to know that the BTC creator made this forum is this true or false?
False. But he was active here, see his profile details:
