Hi jd-1984, I always read through all the answers before I post anything. If there are lots of responses that I agree with, I will try to acknowledge this in my post.
Regarding how I answer, I will always try to make it clear how much actual knowledge I have of the subject I am answering, I would hate anyone to act on any advice/helpful suggestion I have given if it turned out to be wrong.
Like grasscarp and I am sure hundreds of others, I have thought I have been first to answer a question delighted that I can be of help and pressed submit, only to find that lots of people have been quicker off the mark than me!
I think it is because I tend to write novels when I answer questions rather than short snappy answers!
I also try to read through my answer thoroughly before posting to check for spelling and grammar etc, but still find mistakes after I have pressed submit, grrr!!
