I'm not sure if this is in reference to me or not. If it is, then you need to adjust your attitude if you want repeat customers. I didn't join the forum (not yours) to buy your laser, I joined to learn what I can about this hobby and use the info to further my knowledge.
So, if thanking someone for updating me on a purchase who hadn't communicated anything until I asked is spamming, then excuse the crap out of me.
If this is the case, perhaps, you sir, should apologize and in the future communicate with your customers a bit more.
