[dragbike67]

I am a new member and have a ?
How do I do a search In the treads with 3 letters,like FMF, HMF or ATV ?
I see treads with titles like { fmf pipe}.
But when I try and search FMF then I get a message that says there is a min of 4 letters required to do a search.

just put a * after FMF or HMF so when you search it looks like FMF* or HMF*
