I wish I had time to read every page of every thread...but I don't, and like others, will usually just read the first few pages. I will comment if I think I have something that I can add to the thread, but usually don't repeat the same comments everyone else has read. If it is a thread I started, I would read every comment, no matter how many pages, and reply back if it seems it would be helpful. If it is a thread that I have commented on, and wanted more information, I will sometimes go back and look at it another time and see what else has been added.
Thank-you for all that post and read here!
