  • Jay,

    I still can't get over the open acrimony toward SMS-style word abbreviation here. Did any of you that read his post actually have to stutter for even a moment to understand what he meant by those abbreviations?
    Yes, I had to decipher, rather than read.

    Many have stated "I write SMS because it is faster to write" OK, so you one save some time and the many readers will have to spend more time deciphering your message. Thus someone using SMS is, in fact saying "my time is more valuable than all other members of the forum combined".

    People on this board make the most abhorrent grammar errors every day-- Sure, but that is not done intentionally to save time at the cost of others.
