how this site workd

I have been looking for info on how to navigate this site and why i dont have access to some of the stuff.
Found a lot of talk over paranoia but not how to use the site outside of searching for grow info. Once you know what you are doing this site is more of a chat for people with common interest and stories. I dont know what i am doing but i function. Got the best damn tomatoes on the block

Any comments, answers or questions would be appreciated.
Here is my start. I assume as you post you get new tags with your name. Stoner seems to be fairly popular. Is this the case.
Why are there two names. Did people pick them i never saw where i could pick so i am still assuming they are given with teh number of posts.

Why cant i go to the shop or market. Do you have to get special permission or do you have a certain title as Stoner or whatever they may have given you.

Did this site just undergo an overhaul sometime in the week of november 12th my roll it up changed. Before it would show me my last 5 threads and any i had posted on. Now that is all gone. am i being "punished" for something i posted.

Any other newbies wondering how to work the finer sides of this site.

it looks to me like there is nothing there for shop or market maybe they are for future use and not set up yet and i think the name thing is automatic after a # of posts.
