No idea about Dutchy, but do think Imperial59 was posting here when I started. That name looks vaguely familiar to me.
But, hey, after using the name "notin" (which has no actual significance or meaning or similarity to my real name) and no other screen names* since I started posting ESPN, Boston.com, freeforums, talksox, and baseballtradevalues.com for a lot longer than I care to admit, it is nice to FINALLY be accused of having alternate trolling identities. (Assuming this Dutchy character was a noted troll. Was he? And did he share my addiction to parenthetical commentary and ending non-interrogative sentences in ellipses?)
*As I lost the "notin" moniker due to a password snafu on mlbtraderumors, I do now use the alternate ID of "Ketch", which also has no significance...
