TYPO ERRORS! is this valid?

Yes, they are allowed. As long as they are not considered as spam, myLot will not delete the post.

I type really fast too and get my fingers going to quickly for the keyboard to type the letters I hit. I often go back through what I just typed to make sure to correct errors, but sometimes I get to going so fast, it is too late to check for the errors. I'm not sure how it affects us here at mylot. I'm definitely guilty of this also.

I'm not sure how they deal with typos. I've made quite a few typos myself. My keyboard has some of it's letters erased so it's real easy for me to make a typo hehe.
