This is not the usual run-of-the-mill question I see on DC, so I will respond with more than the run-of-the-mill answer.
First off, following April (app103) is a tough call. She really expresses the "feeling" I would try to convey, so I hope I won't be redundant. I do have a thing or two I would let on about. Hopefully, the meaning will come through.
Sometime back I tried a pretty radical experiment on DC. Some caught on to what I was up to, but most interpreted it in a way I that caused no little grief for themselves and me. I really did shake the joint up pretty good and I would not do it again, but that is not the point. The point is that after I made my amends I have not suffered one comment being "thrown back in my face" about that snafu. No one has ridiculed or ostracized me; on the contrary, it is if I had never taken my misstep. I feel as welcome today as I did the very first day I ever posted 3-1/2 years ago.
I am over fifty. I have been messing with computers and the Internet since 1994(?). I have been a whole bunch of places and participated on a lot of boards and there is no other forum I have come across that "feels" the way it does in Cody's Home.
There has never been a question I have asked that was not answered in a way I could grasp, albeit sometimes it took a few laps around the track. Every suggestion I have made was given a fair shot even when some were not so bright.
An excellent resource for great software and outstanding coding education. No one will babysit, but there is always a hand-up when it is needed.
Lastly, due to certain events that have happened in my life, I have come to know the existence of Yahweh (God) in a way that can never be shaken and many core members here know this is true about me. This fact may seem anemic unless you understand that many, if not most of those core members are Atheist in their beliefs and one has stated to be a "Vehement Atheist." I do not "preach" at them and they respect me as an intelligent human being. There is a harmony, a peace which reigns over this camp and it is very sweet. The truth is (hopefully not to their chagrin) I have learned to know more about Yahweh (God) and His true nature through them than I did going to church since I was a child. I have invited many of my God-loving friends and acquaintances to come to this haven, but sadly their spiritual prejudice was great and I could not convince any to "taste and see it is good."
You asked, "What is DonationCoder and What Are You Doing Here?" The short answer for "where," ironically, is "Heaven" if you count relationships with human beings to be the most prized possessions a person can have. As far as the "what?" Well, I am learning about a lot more than programming, growing into a lot more than a solid technician, maturing into a lot more than just a man and loving a lot more than I ever expected.
I never expected what I am today to be what I expected when I made my first post here some 667 posts ago and I can't wait to see what I will become by the time I have made 667 more!
I hope that answers your questions.
