Great link, Invigor
I, too, have trouble understanding some posts. Some posts are by younger members who write in Internet-ese, or whatever it's called, and other posts are by members who should really know how to spell better.
Of course, this board and others like it are not English class. There will be a certain portion of posters who are excellent spellers and others who are not.
Bottom line for me is that if I don't understand what a poster is talking about with relative ease, I ignore them, no matter how much I might want to help with their reef related problems.
Gads, look at all those run-on sentences

Did anyone understand what I was saying???
