The great thing about FT is you often have an idea about the background of the folks posting, either via personal contact or mutual friend FT'ers who know them etc.

Many of us I am sure could readily home swap on vacations if enough lead time were available via such a Forum. I have a 3 story home on the Harbour here I leave vacant as I cannot be bothered renting it for a few weeks a time etc. Others I am sure likewise leave their place empty when away.
