not so much here, but on a couple of other forums, if i've been involved in a lengthy debate with a poster, it's grown late, and i am falling asleep over my keyboard, i will definitely post something along the lines of "hey guys, late here, and it's gonna take me ages to get the keyboard impressions out of my forehead. off to bed, will be back in the AM." i want them to know that i'm suspending the debate due to eyes closing and brain clicking off.
i have stated something along the lines of "okay, this ain't working, i'm out of this thread." i did it once here and was reminded by a mod when i came back a day or so later that i had declared my intention to leave the thread, so it might behoove me to adhere to that stated intention (paraphrased).
a forum that i was a member of a few years back used to have flounce threads. we required pictures of appropriate flouncing costumes. it was a contest to see who could find a picture of gowns with the most, well, flounces. that happened after several posters did the whole GCF thing and flounced off in high dudgeon.
