I've seen poor spelling and bad grammar all over the 'net, and this place is no different. Why don't we all take the time to put down our thoughts carefully and clearly? Major sponsors are interested in sites that reflect positive values, including decent, respectful discourse. That's my two cents; I'm sure I'll hear about it.
I can tolerate bad spelling and such. But knowing I am judged by the words I use I do what I can and believe me, I need all the help I can get. I graduated in the top half of the bottom ten in my class! (no joke!)
There is also a great free version of a dictionary and thesaurus called WordWeb. http://wordweb.info/
I highly recommend it!
