I prefer one board....with descriptive titles for each thread.
I don't use ATX....so if it's an ATX issue.... I skip it.
I don't do business returns....so again, I'll skip those threads.
If it's a personal thing that interests me.... I 'll read.
Tax questions... I'll read.
Complaints about clients.....well, misery does love company!
It's just easier for everything to be together....and then you pick and choose.
