where number is optional parameter to limit how many oligarchs show, defaulting to 5 or 10.

Is it possible to realize? I don't know Java so it is problem for me to fork repository and do it myself.

Sorry. I've been pretty busy. I could implement this but it might take a bit because I'll need to limit the amount of top accounts you can see. I'd also need to add in pages for more than around 10 accounts.

I believe it should be simple task, just for pages add LIMIT with 'offset' in query:
SELECT * FROM {database}.{table}
ORDER BY money DESC
LIMIT 10 * {page}, 10;
