I recommend reading / understanding the rules of the board.
EJ board is a place where moderators want to encourage quality over quantity. Capitalization and punctuation are not voluntary to keep the quality/readability of the board high and overuse of internet acronyms is also frowned upon.
EJ can be a fun place to read and post, but the fun here comes from different kind of things than on most other forums. It doesn't come from posting lolcats, icanhasvariousdifferentburgers or other internetphenomena, but from intresting posts that actually add useful an valuable information to the discussion.
Some people do actually enjoy math quiz'es, quantum physics, and breaking things appart to find out how they work. We like to break Wow appart, go trough the debrii with a fine comb and analyse every bit of it to find out how it works etc.
And no, people here are not generally elitist jerks that take enjoyment from banning / giving infraction. Our enjoyment comes from quality discussion, so we naturally want to protect the board to keep it clean and neat.
Ugh, I really made EJ'ers sound superserious. Fun just doesn't mean that we need to spice up every post with "words" like: some1, omg, lol, wtf,

DDDD and whatnot. Jokes are more than welcome. Flaming is not.
edit: Someone seems to have done something really "funny" to the post above this one.
