Hi Steve
I really hate it when people pick fault, it really shows that they are ignorant. I have had a few flair ups on this site and all over public condemnation of questions or actions that have been taken by a member. It's all about helping people and encouraging youngsters to fish, just as I was encouraged years ago.
I work in the R&D world and we write heaps of technical reports. Before we issue a report we send it to a colleague to proof read before it goes out. It's amazing how many highly qualified people make mistakes in spelling and grammar and my excuse is that I get wrapped up in the detail vs the delivery. A fresh set of eyes can see more!
Anyway, keep doing what you enjoy and keep catching.
