A lot of work awaits the support staff to clean up the duplicates, perhaps you should employ some people
I hope I am not the only one cherrishing your great efforts!
Although your server is pretty fast for me (took only 32seconds to generate ?page=maps&l=all) you might think about pagination, splitting results on several pages every xxx maps.
So let me tell you about several 0 byte files - take a look at those map for example. Maybe the upload went wrong? Some are your own uploads I guess, because of the date "01.Jan.70, 01:00".
Could you explain the new introduced mapformat? The maps I have checked indicate number 4, what does it mean?
Regarding the <<a bar which displays the percentage of gras/desert/jungle or winter main tiles>> I have to think about it and maybe need to generate some more preview images to understand
Last review for now: in single map view I see CRC32 information, but additionally I would like to compare filesizes - could find this on gametype view only. Perhaps you consider this is as insignificant?
Thank you for all the time you spend programming this site.
