I can see both sides to this discussion. One thing I have done, just today as a matter of fact, is to leave greetings on the message boards of members' profile pages so that, although their posts have so far gone un-replied to, at least they don't feel completely ignored.

Also I just want to add here that while women only are supposed to post in the women's forum, & men in the men's forum, & teens in the teens forum, cis-gendered members seem to feel it is appropriate to post in the transgender forum. And I know there have been trans members who would prefer that this not occur either.
