must say , you guy's have some interesting idea's here .
Getting folks more interested in the area has always been a challenge for all site's and no real simple solution . GB are a good way to go but sometimes limiing to only one kit manufacter folks lose interest in the idea . Including others will give more options for folks to join with . Yes WNW kits are popular , but not ever one works in that scale and they still have a limited section for now .
I'm a WW 1 nut all the through , many projects on the go at the moment . WNW SE5a , Rodens Sopwith 1 1/2 strutter on floats , Eduards Pfalz D.IIIa , Rodens Pfalz D.III being super detail and Lone Stars FE-8 which only three parts used from the kit , everything is scratched on her so far this is a work in progress on the drome and areoscale . Stalled at the moment do to other commits .
Maybe step by step tutiorals on weathering , rigging ( I'm a master at this ) and detailing letting the folks know that this really are simple kits to build . After reading post on other forums these seem to be the main area's folks struggle with .
You could also have a contest . Like most well known site there is lot's of product which comes in for reviews everything from kit's to accessoires and me spelling

Those items can be used for prize's and such -just an idea .
When I first join Areoscale I had contest just for us ladies . We posted 5 kit's in the stash and the members had to choose which one we built for the contest , can have something like that here ...
any way I'm talking to much ........
