HI - do you seriously expect this forum to tolerate all your 5 different alter egos? As we all know, one of you is enough!

Sticking to HI was ok though, it's got a fine ring to it. Nice pick!
well, I only read the last two pages, sorry, no time!
burrahobbit,Lush,Estelyn Telcontar, Squatter of Amon Rudhwere already mentioned...
Some new ones I like off the top of my head: The Perky Ent , Sleepy Ranger- cracked me up the first time I saw it

; also I like the guy who would be short, and there was once someone (I haven't seen him for a while, though) whose nick was The Rip Designs Dude, and his hobbit name in the ME Name Generator was Pippin Took - how cool is that? Of course he boasted of it all over ME Mirth - or was it Novices and Newcomers?
But seriously now - Pink Viggo?

eh...
