Word is valuable for its spelling check, but as for grammar, I recommend you check that yourself or use your discretion. Word Has a habit of trying to fix such things as passive voice, fragments (that you mgiht want to remain as fragments), wordiness, word order, and how you might chose to begin a sentence. If your computer is using Microsoft Word 2003 (and any other edition, potentially, but this is one I am sure of) you can access the autocorrect options through "tools" and scrolling down to the icon. This can make your post proofreading easier.
A techinque I often employ is first formulating a mental image of what is happening and let it play in my head. You must make it as detailed as possible, see it as if it were really there. Then, as if you were telling a story, describe it to the other players. For a story to be effective, there must be a good deal of description and it is generally understood that good tales make sense. This may help in the flow of your posts.
I will also recommend two useful links.
dictionary.com and
thesaurus.com , these links are both helpful, but I suggest you do not abuse either one.
