My personal opinion (for what it's worth, which may be nothing!) is that a low post count is NOT a reason to avoid a renter...we all have to start somewhere...and as someone pointed out, I've got a low post count, too (or at least I did before all this started--grin!)...
It's a sign that some further caution may be required...to be sure the person knows how to do a rental agreement/transfer, for example. But just because someone is new to posting doesn't necessarily mean they're new to renting. And even if they're new to renting, that doesn't mean they haven't done their research and know how to do what they're offering to do...and even if they're new and learning as they go, good communication between the person offering the points and the person wanting to rent the points will solve most problems...
So, to me, a low post count is just one factor to consider when deciding whether to go forward.
I also feel compelled to point out that this "PP" has a history of difficult, but ultimately successful, rentals...The VogelFamily DID get their vacation on the PP's rented points. A previous poster noted he'd rented from her four times (via ebay), successfully. It may well be that she's learning a hard lesson here, too...that a successful rental agreement requires more communication than she thought necessary. Maybe she's feeling defensive now. There's certainly evidence to support hope that she will in fact return both my money and StaceySaulito's...just not as quickly as we think is warranted.
The whole point of this thread, originally, was NOT to "trash" a problem poster, but to point out the kinds of steps that can be taken that can avoid this type of problem. I do see the danger here of so "attacking" the PP that she throws up her hands and "runs away." She still has a chance to make good on her promises and to do the right thing. She may still do so. There's no way, even if Disboards would allow me to, that I'd post the kind of linked post that has been suggested. To me, until and unless she actually welsches on her promise to return my money (and StaceySaulito has to make her own decision on this), that would be unfair and unwarranted.
Anyway...we'll see what happens. I used to tell my son when he was little that we need to learn how to practice "the P word" (patience)...this has yet to play out to its end. There's still more hope than not that the "PP" will return my money (and Stacey's)...I'm not going to start accusing her of crimes until I'm certain a crime has been/will be committed. Right now, she appears to me to be more likely to be guilty of being inconsiderate and "difficult" than criminal...
