I've bought a new laptop and recently re-joined this group when I had my old one. I've never knowingly done that, all mods have to do is delete one account. I've not used different names upon registration. Maybe I posted from my phone and that has my old details? I didn't even type in my username and password, it auto does it for you from whatever your posting from.
FFS I'm not trying purposely to have 2 accounts, I'm 61 and admittedly not I.T. savvy. Am I using the two accounts to prove an argument? Any dummy can see not. If I am trying to be deceptive, would I post using one name and respond using the other? As you say, gives the game away somewhat doesn't it.
And you and 2 others want me banned for that! What a friendly accommodating bunch.
