Stockprofitter - that is insulting personally, and you have no idea what you are talking about.
Additionally, Lumpina has shown himself to be a person of integrity in allowing your acknowledged debt to him to be paid as a donation to Investor's Unite and you, if you have any personal sense of honor, need to follow through on that acknowledged debt and accept the offer to donate to a worthy organization.
You can have someone at Investor's Unite send Lumpina an email confirming your donation of $300.
