I was a member of both, and now a member of neither. Since I dropped those memberships and moved to LA, met a few people, and done some good quality free work - I'm busy with paying gigs. Taxi is a music req listing service. Many film reqs that come in are for band songs that folks are looking for as "vibe-alikes" to popular tunes. There are some "I'm looking for an orchestral composer" kind of listings, but those are few and far between. FMN seems to have started as a way to get new composers to understand the film business, but seems to have stumbled a bit. I ordered "Welcome to LA" - a kit that included things like how to register your studio/company/services as a business in LA county, etc. - and it took them until I had been here more than a year and had already moved once by the time they got it to me. They may have tightened things up considerably since I left, but it's been off my radar for about a year now.
