discussion among solo traveler

I am 68 year old female who travels on RS trips solo---because my husband has not yet retired---and I would like to know if there is anywhere on this site that solo travelers post a little bit about themselves and what trips they are contemplating so that other solo travelers might get to know others and perhaps plan trips together.  I have seen this on discussion boards on Rick Steves travel website, but have not found anything similar on this site.  I love to travel, and will travel solo by necessity, but would much prefer to meet others and travel with someone I know a little about.  I have limited funds and cannot usually afford to pay the single supplement to stay in a room by myself.
