You may have been "Doc" for many years outside of the online community and that's fine. Maybe you are the only "Doc" on the sewing and gardening forums so it works there. I personally know 3 different people who go by that nickname, but there is only one who is on the detecting forums. Doc may not have been known by that handle as long as you have, but to all of us here in cyber space on the gold prospecting community, he had it first. And it's only common courtesy to respect that, especially since it's his name at the top of the forum as as the moderator. I would respectfully suggest you change your online handle to "Ole Doc" as you signed your last post. It helps everyone to know who's talking when they see the tag line and avoid confusion. For example we have on all the forums "Grubstake" and "Old Grubstake". No one would confuse the two when seeing the names since they are ENTIRELY different people. What they have to say are very different but without the distinction of slightly different names, there could be some very nasty conversations until it got cleared up.
Thanks,
