I do come from Robox, but do not play it much...
It kinda sucks now... =/
Ahaha, i don't blame ya! xD
Anyway, be nice, don't spam servers with a bunch of pointless bricks, don't annoy people, if people annoy you, the server admin should notice, if they don't try telling on the annoyer, if the admin doesn't respond then he/she is most likely not paying attention or is afk (away from keyboard), if you ever learn how to make decals, make sure they're actually good, even if it's your first, if you think it stinks even a TINY BIT, people will flame you for posting a terrible decal, though sometimes they may just tell you to improve or whatever, don't be bothered by anyone who may bug you for having a high BL ID when you buy Blockland, there's nothing you can do about it
And the last, most IMPORTANT RULE OF ALL... Have fun :D
