Just wanted to say it's incredible to be able to see the changes to infrastructure happen in one day with no interruption to the service. Way to go pyramining!
Pointing new miners to a Pyramining address is not much work. Last week I had to upgrade the server and I caused at least 20 minutes of down-time (only to the web interface, mining equipment was working correctly).
Also, pyramining, I had a question about referral links: is there a chance that an account could have just one link, that unlimited amount of investors could join through? Or is this something that you intentionally designed like this to prevent abuse?
I intentionally designed links to expire. There are several reasons for this, for example, it wouldn't be nice if someone posts a link in a "lucky" place that comes out as the first link on a google search: he would get a lot of referrals while others not. Another reason is that it would be a waste of resources if someone posts a link somewhere, his account gets completely rewarded (and then inactive until he deposits again) and he still keeps getting referrals without gaining anything from them due to the "inactive" status of his account. I think that this way is better, everyone has to actively "grow" his referrals portfolio, keeping an eye open on what happens.
