Mine was due to a stroke. Is it possible for you to write your posts off line in for example MS Word? Then you will 1) have access to a spellchecker that might help in removing typos when intention and hands don't agree, 2) be able to, when ready, convert the lot to lower case using the F3 key. If sentence initial letters won't be capitalized, I suppose nobody would find it unusual. There are lots of posters on the 'net who don't use capitals. Insome cases, the reason might be that their native script makes no upper/lower case distinction.DUE TO MY BRAININJURY
There's a fascinating variety of "r" sounds. Being fairly familiar with the Swedish assortment, I find it easy to imitate the flapped Spanish r and its rolled rr, as well as the Parisian (or German) r. On r's, there is an interesting way of using them in a variety of Swedish: As initials, they almost resemble [o] or [w]; in other positions they are regular flapped IPA[r]'s.
And don't make any conclusions regarding my preferences, just because of my interest in the use of the r's.
When not writing in my capacity as a translator, I freely break many rules that I was taught. And I love starting a sentence with a conjunction, not solely to parahprase/joke with Old Testament translations, but because I think it often makes sense. And fortunately, we never had a rule like Safire's Fumblerule #49: "Never Use Prepositions to End Sentences With." But one should never generalize (9).
Last but not least, avoid cliches like the plague. They're old hat, seek viable alternatives. (39)
