jr? The choice is ultimately up to you to stay or go. I would prefer you stay, as it might be helpful in a number of ways. One to improve on your magic, and perhaps help improve your dyslexia.
I agree with what other have said. Use a word-processing program to check your posts (i use them quite a bit). And look into a talk it, type it software. I know people who have used them, and have been very happy with them. I will check to see what brand they are. PM me if you would like more info on that.
However, in life, magic, career, whatever, you are going to run into people that understand you, and people that don’t. For you, having dyslexia, obviously, you will run in to a lot of people that don’t understand you, and will act negative towards you. Such is life. But don’t let that stop you. Keep working away at what you enjoy to do. I think one of the best ways to overcome dyslexia is to keep training your mind. What better way than learning and practicing magic. So my opinion is stay with T11, try some of the suggestions mentioned to you. Hell, PM a couple of friends with your ideas before making a post, that way they can help structure your ideas.
As for other T11 members... I respect jr? for trying, I can't imagine how difficult things can be for him. So here is an idea, if you don’t like what he has to say, do not read his posts....simple as that. It upsets me to see posts asking to have him banned because he is trying. He had told us up front of his condition, so you just have to work with it. So, can we jump off our soap box, and abandon this odd sense of entitlement, and maybe lend this guy a hand. After all, T11 is supposed to be a community to help magic and magicians, not boot them off because you don't like their posts.
