I HATE this sort of thing...misinformation... I've found that Ti-HAs are the WORST about doing this. I'm like hey if you dont know, just say you dont know and i'll go look it up or ask someone else, why give me bad info??
Then, when I am asked something and i dont know the answer, such people look down upon me for saying "i dont know", but how else will i find out, i mean i wont learn if i keep going around pretending like i know everything...
