@ehBeth,
Sugar! Do you remember, back when the earth was much younger, we lost the member named Sugar, and for the exact same reason? She posted a non commercal link to a web site of her own. She got stubborn; Craven got stubborn, and she left. It was far from being her first post.
So far as which travel diaries, or whatever are acceptable, I guess any that aren't selling anything, and don't infect your computer would be alright, but so far as virus goes, the only way I would know to find out would be to click it and see if anything bad happens right away.
