Since I don`t see a "contact us" link (which may in fact be buried somewhere; I didn`t dig too hard), this will have to do to offer a suggestion: It would be helpful to have the option for new members to use either the username of members or their ID. In recommending the site previously, I gave my username but only later realized that it`s not enough to get credit. Also, it`s generally easier for someone you meet to remember a name than to remember a number (even assuming you yourself remember it to give out!)
