for me at least, its not how much you donate, its that you donated, $5 or even $1 if fine, its really about showing support.
bossland does support our coders. he knows that the plugins and CC's are making this thing. a while back this was almost a year ago, i sent him a pm and i was like "hey im having to take time from botting my main account to develop these plugins and stuff i was wondering if it would be possible to upgrade my sessions if i had at least 2 i could develop and bot my account" (this was after i released Project Gamma, and Codename: Frozenheart) he was nice enough that he upgraded me to lifetime for free. but you gotta remember before i made those CC's mage botting was horrible, so just having them and keeping them developed was (to the company) well worth the price of lifetime, and he knows that. he wont pay you right out, but if your like "hey i cant develop anymore, can you help me out" if your a good investment and have contributed. he will help you out.
im not saying beg to bossland for free shit, but if you truly think the work you put in is worth it, then it never hurts to ask.
