As it has only been 9 years since I began crunching for the TeAm I am not sure that qualifies me as an "old fart"... however I have definitely been in hiding the last few years, I am still way under 1000 posts on these forums.
I do have as many computers as ever crunching away, currently 7 as I write this post. But there were long periods where I didn't have anything running at all, such as the 2007-2010 period where I was moving around the country constantly looking for work. But it was always in the back of my mind that I needed to return to the TeAm some day!
Favorite DC memories over the years:
1) Secretly installing F@H on my father's Pentium III computer and then trying to convince him that he needed to leave the computer switched on at all times because it was "good for the circuitry"
2) Seeing the huge, mind boggling point totals the first time I started running GPU WUs... what had I been missing all those years on CPU-only DC?
3) Lunch with petrusbroder in Stockholm in 2006 while passing through Sweden on vacation!
While it might not have cracked my top 3 all-time, the PrimeGrid contest to kick off 2013 definitely gave me a feel of some of the "good old days", let's keep it up TeAm!
