Isn't it a little redundant to ask whether you can bump while a thread while you're effectively bumping it? Sorry, it just something that came to mind.

Anyway I have some thoughts on the thread. The first option is something I was going to suggest as well as I'm also into cartography. The second option tends to be found in threads in both the reference material, general discussion and misc mapping sections so I don't think it's really necissary. The third option however I don't think is entirely appropriate for this site as it's not really directly related to cartography.

Just my thoughts.
