Thanks for the reply. That info makes sense, but it also appears to creates a potential gap in the search capabilities.
Many items listed are commonly referred to with 3 characters that, based on your explanation, can no longer be identified via the search function. For instance, M10, M11, MAC, MP5, UZI, M60, 249, M16, SP1, SBR, SBS, AOW, SWD, M50, DLO, STG are but a few that are commonly searched for in the NFA Forum.
Will those posing be instructed to use new key words that are 4+ characters so they can be searched, if so, will those items be standardized to make things easier for those browsing the forums? For instance, instead of M10 use MAC10 or instead of MP5 use HKMP5. This would work in some instances, but not all.
I apologize for all the questions, but I'm new and am trying to figure out how to effectively buy and sell in the new format.
