I don't know if this exists somewhere on the forum; I also have no idea if this is the correct place to post this ( ;) ).
We often see posts containing code without code tags, hyperlinks that are not clickable etc. Most of this can be done using the 'advanced' editor but except for opening posts, most people seem to use the 'quick reply' or 'quote option' and hence hardly ever see the 'advanced' editor.
This is an attempt to have some common bb codes in a central place as reference.
[code]your code here[/code] gives
your code here
[url=http://forum.arduino.cc/index.php]arduino forum index[/url] gives arduino forum index

Sometimes you want to draw attention to a specific part in the text
[b]bold text[/b] gives bold text
[i]italic text[/i] gives italic text
[u]underlined text[/u] gives [u]underlined text[/u]
[color=red]red text[/color] gives red text
Sometimes one wants to correct a (small) part of text in a previous post after a comment made in another reply. To keep the original more or less intact so the other of the comment does not look like an idiot with a misplaced comment, one can use
[s]red text[/s] gives
And lastly how to prevent the forum software from parsing bb codes while not using the code tags
[nobbc]pinMode(pinArray[i], OUTPUT);[/nobbc] results in
I case you did not know, bb codes can be nested to e.g. create bold green.
There are a few more, but those are the ones that I often use. Please feel free to add ;)
