No need to be sorry bro, what for should you be sorry? For spending countless hours and days getting this tool to work so others can start using it without inhibitions, exhausting or flooding the server with requests (just like I did a moment ago probably;)) and then blame the tool or its creator :) I happen to know just a little about all that is involved with coding this stuff, so I know you spent a lot of time getting this thing up and running.. That itself is amazing, and not done on a lazy Monday, another thing that makes it more amazing is that this functionality is simply being offered by several sites which require a paid subscription. I know, since I am a paying subscriber on numerous sites and boards. I have to pay to make up for my lack of talent :) But what I lack in talent I make up in appreciation so thumbs up dude!! And I won't make many friends by my next statement, but that is okay, it teaches me to cope with a lack of friends as well: consider a small contribution one way or the other, because I don't think you can rent servers without paying for them yourself. Again I'm quite sure I am right :)
Regards from a beginning python coder who will never come even close to your league :)
