That's so true :) But I have to learn English first :)

Seriously, I have 100% spelling sense in Russian, and I have a good visual memory for words, so I catch spelling errors and grammar's errors, but usually just don't correct them here, since it's not the objective of this forum :) When my husband writes a message and allows me to read it, I correct all mistakes.
