Hello All,
I have a slight update to my previous message here. While I have no
intention on returning to development at full capacity, from time to
time I do have some ideas worth testing. I am still a heartbroken man
but I have to pass the time in some way. I do not know how long I will
be around for, but maybe I can find some improvments before I am gone.
