Nevertheless I thought about the usefulness of
cleaning threads from such posts, as they make searching even more difficult.
Why so? In what way would a "Thank you" message complicate a search? I don't understand it.
I tend to think that spelling mistakes in thread titles ("chinise" instead of Chinese) or wrongly constructed aircraft designations ("F-6F" instead of F6F for instance) are much more harmful in this respect. Indeed, given the amount of visibility this forum gets and the insistence on usefulness/accuracy around here, I'm surprised that the mods do not intervene more systematically on the topic titles.
