While the majority of my posts are regarding authentication, I have posted in other other forums as wel since joining tpf (primarily the forums sharing photos wearing different bags, etc).
Unfortunately, I'm trying to find a birkin for a christmas present, so given it will be most likely an ebay sale, I don't have time to use an outside professional authentication service (as it is from my boyfriend, for myself, as he put off buying presents until the last minute, as always. Sadly, I doubt he would bother with an outside authentication service, as he won't even be bothered to get bags authenticated on TPF). The majority of my recent posts regarding authentication (chanel in particular), were on behalf of him, for his mother's present, not for a purchase of my own.
I practice law, am adamant about IP rights and strongly against the counterfeiting industry, therefore, obviously do not want to further the profits of the counterfeiting industry, but I guess he'll have to, since I know he won't bother authenticating anything himself.
