I want to share my build, but typing in and linking every piece of equipment/component/augment is too much for me. I see people sharing pretty build in BB code, with and without items bonus as well. How do I do that?
If you click the quote button beneath the post, you should see the BBCode in the message box inside the [quote] tags.
There are a few things at play here, like ibugsy said, find a forums post you like and reply too it to see what kind of bbcode was used. But since you mention builds, I bet you are looking for GrimCalc and GrimTools type sites, check the forum main page community box for links to those and other tools. And finally, you are probably refering to images of builds, which can be made from screenshots either in game or of your browser window when using a build calculator.
Both build calcs let you save and share the build via direct links. GrimTools also gives you to option to load your save game file to jump start the build creation and gear up with currently equipped items.
