I'm appreciating and gladly using all of the PGC features, especially since I've turned paying member few years ago. You are getting closer to the perfection.
My concern at this moment are the logs edited on the geocaches I own. Even though there are not really much of them. Do not considere this any request, please. Rather a pure question.
Would it be technically possible to include the genuine logs in the emails sent by the "Edited logs notification"?
Well, I know, I can compare the new, edited log with the genuine one, saved in my mailbox. Still it would spare my time, if I saw both in one email and so I could get the info immediately and get the clue, what and why has it been changed. Especially if it happens with few years' old logs.
I found one older related question: http://project-gc.com/qa/?qa=152/why-doesnt-edited-log-notification-show-original-log&show=152#q152, but this one was asked and answered in September 2014. And really much has changed on GC and PGC sites since then.
