I am really sorry you spent a good amount of time trying to figure this out. As a user, you do not have the ability to modify topic lines.
I mark items [Sold] whenever I see a post in a for sale string indicating an item has been sold. This lets everyone know.
I like leaving the threads as it provides people with sense of what is out there, prices, etc.
No harm. (I do stuff like that all the time these days, it seems! I tell myself that I ought to be able to figure things out, just try this and that and the other.)
And I could’ve sworn that I had marked something as sold here on the forum. (Ah, maybe US Audiomart, instead.)
Thank you, Elk, for the addition in re: “sold” to the PCA-2/HCPS listing. (Now, could you convince somebody on the forum that the Cullen-modded HCA-2 is a great deal?
Best regards, Chaz
