Somebody is trying to reach you.
BladeForums and other similar sales sites have been plagued by scammers who post or send emails pretending to be a seller.
Do not respond to emails. BF does not disclose email addresses to members. Wait until the seller responds in the thread.
A favorite trick of scammers is to create an account with a name that resembles the seller's member name. Then they post in the thread and pose as the seller. So if someone posts in the thread, check their post count and membership level before believing they are who they purport to be.
Sellers can repost an item in a new thread after 14 days. So posting in a thread which is older than a couple of weeks has a low probability of success.
