Anyone who has been in the Notes/Domino community for some time knows Nathan T Freeman, also known as NTF. He was one of the founders of OpenNTF back in 2001, and has been blogging and presenting on Notes and Domino related subjects for many years. I have learned a lot from him over the years.
Nathan has always been a very colorful person in the community. I just found out that Nathan is having some serious health issues. His wife Lisa created a GoFundMe to get some help with the medical cost. If you have ever benefitted from something Nathan wrote on his blog or talked about at one of his many presentations over the years, or if you used OpenNTF as a source for code, consider donating to help Nathan and Lisa.
