Tracer,
Don't worry about typos and misunderstandings. They are constant on the Internet in all forums just because few of us are professional writers.
As to your problem, go ahead and compose large on your word processor. There is a way to fix the size here in the advanced composition window, but the easiest thing is to take your word processor copied text and paste it intö Notepad, then select all and copy it again and paste it intö the composition window. The intermediate copy removes all the funny faces and other stuff the word processor's invisible formatting characters create. You will need to set Notepad's Format button to turn off Word Wrap. This makes your text lines go off screen to the right because of length, but that will be corrected automatically when you select it all, copy it, then paste it intö the forum composition window. If you don't turn the Word Wrap off, that adds invisible carriage return characters and they will make extra blank lines in your pasted text. You may also use the Notepad format to change the Font to Verdana so it matches the board font if you want to?
Once you have pasted intö the composition window, click on the Go Advanced button. That will give you a couple of font tools in the tool bar at the top for changing the text size. You just select all your text and change the font size to 2 to be normal for the forum. Sometimes I have to first change it to some other number and then back to 2 before the size control takes, but that's the only bug I've run into.
