in your current plugin library, here is what i would do instead of you:
1) make a server multiplayer Server using DarkNet or Multisync
2) all that data you collect, save it as TXT file:
e.g:
Player1: 4000xp/ level 5
Player2: 5k xp level 6
and so on.
or you can save it as HTML languange, doesnt meter.
now, get some free domain + hosting that got an FTP access,
using Darkbasic own languange, connect to that FTP, upload your html file as a webpage, and here you have it.
so as you see, it is possible to do just how you want it.
it requires a lil bit of coding though.
but i suggest you to do it step by step;
1st, create multiplayer game, even a basic one. to see how the server/client works.
and then move on to the next level.. just like i said; create txt file and upload it via ftp to your webpage.
good luck.
