Thank you for your appraisal, www, em, DominoKing.
I imaged "Human Network" & "Social Network" besides the "IT" term.
Retrieval result "Network" GOOGLE : 1,570,000,000, so various possibilities.
Now, "Forum" is hot keyword for development community site with vBulletin.
I think these kind of domains demand goes up.
Thanks again.
