Why "Challanges signed" consider only "write notes"?

Question

Cann you add the field "personel notes" for the new tab challanges?

If you consider only "write notes" in the logs, I'm afraid the logs will contain more "write notes" in the future than "finds".

Yes, that were greate.

Answer 1

I would say that it somehow common sense, that you "log visit" by some kind of "log", not only by "personal note", so also the owner has a record that you were there, even if you did not write "found it" log. Also it is more widely adopted, because the "personal notes" are available only for premium members and therefore not applicable for all players round.

... so also the owner has a record that you were there, ...
No, I wasn't there. I use this only for me, to remember that I will go there. In my opinion this is not relevant for the owner or other cacher and therefore i write it not in the log.
Anyway: It is only a game.

"Challenges signed" means that you were there and did not fulfil the requirements yet, so it is for both you and owner (and therefore the WN is appropriate). If you use personal note to keep track of challenges that you fulfil, but did not visited, it is something different than this section is supposed to do.
This functionality is referring to the point 7 in the official guidelines:

If you intend to use it to something different, please clarify that in the question.
