From the forum rules and guidelines:
Would this principle apply to all-lowercase, little/no punctuation, and AOL/texting-style spellings (e.g., "u" instead of "you")? I have been subjected to several postings lately that follow the aforementioned pattern, and it has about the same effect as all-caps l337 on my sensibilities and parsing of text. It's not a huge deal if there's a typo somewhere in an otherwise decent post - I don't even register it half the time - but whole posts with no Shift key usage and phrases like "u 2" might as well be in Comic Sans, just for good measure.#5 - Please refrain from typing in all caps or using text speak or "l33t speak" (e.g. (***, @@@, DjCo0Lb1tCh) especially in the subject lines.
