It would be better if the overall "feel" of FlyerTalk was a bit less "hostile" to the newbies... For example, there are no avatars which 99% of other forums would allow- even if it's just one specific issue it does play a role in turning lurkers into members.
As for the technology issue, I think what we have works. Perhaps a slightly enhanced software/forum server package could be beneficial, but FT shouldn't "degrade" itself to the Facebook-style layout.
