This is how I read the forums. The most recent is shown first and they descend in the order posted. It is a mix of all topics. I have not been posting on the boards all that long compared to others. Until more recently than I hate to admit, it did not occur to me to select a category from the menu to read posts. I knew to select one to create a post.
I am so bad at technology. What may be obvious to others is a mystery to me. I certainly did not realize until today that not everyone sees every post because they have specific categories they use. I am on an IPad. I cannot use the forums on my phone and have never tried my computer.
Last summer I did an all day progressive post under Sports showing a big soccer tournament and the wild horses having to wait for the field. Some of the regulars who enjoy the horses did not respond. Now I think I know why. By the time I get good at this, it will be too late.
