Jaime, first of all, my apologies for thinking that since both posts you made after joining were to promote a particular operator, and your location lists various places that company sells tours for, you were affiliated with them.
Jaime, since you are a new contributor and you didn't introduce yourself, we're left to guessing. It seems my guess was wrong (but I don't think it was an entirely illogical conclusion to come to, given the circumstances). Most people on SB are men, so statistically the default assumption, since you declined to provide your gender in your profile, would be to guess you are male. That was also apparently a wrong guess. Once again, my apologies for guessing wrong.
As for why people send PMs, they usually feel that the minutia of their travel plans and preferences is of little interest to the general readership.
