The first part of this is not an issue - you are no stranger here, but even if you were, you have to start somewhere! My point with sharing that advice was basically, if you don’t get a lot of engagement after your first trip report, don’t despair - it takes time for people to get to know you. My first trip report only got 16 likes! lol
The second part of your post is completely understandable. If you prefer to post when you get home, I’d love to read all about your trip! Either way works.
