+		Hello everybody out there using minix -
+
+		I'm doing a (free) operating system (just a hobby, won't be big and professional like gnu) for
+		386(486) AT clones. This has been brewing since april, and is starting to get ready. I'd like any
+		feedback on things people like/dislike in minix, as my OS resembles it somewhat (same physical
+		layout of the file-system (due to practical reasons) among other things).
+
+		I've currently ported bash(1.08) and gcc(1.40), and things seem to work. This implies that I'll get
+		something practical within a few months, and I'd like to know what features most people would want.
+		Any suggestions are welcome, but I won't promise I'll implement them :-)
+

+
+		PS. Yes - it's free of any minix code, and it has a multi-threaded fs. It is NOT portable (uses 386
+		task switching etc), and it probably never will support anything other than AT-harddisks, as that's
+		all I have :-(.}
