It's indeed a common etiquette to avoid multiple posts on internet forums. I often enter some threads and edit them to merge double/triple or mutliple posts., especially on basic multiple posts that could be prevented with a simple edit or on multiple quotes posts (which I think it was the case in your thread) - of course, not on the WIPs posts showing maps progress, mostly in order to de-clutter threads and the right forum window.
I do that when I see them, I'm not all the time connected on the Guild forum hence i go through the ones I spot. I probably miss a lot of them. So nothing offensive or personal here Chick
