Yeah, both splits have sorted a lot of shit out for all parties involved. This forum is predominantly a US forum, there was an issue between the US admin and some of the Aussie moderators, so the Australian Ford Forums were created. The E-Series Owners Club (which was hosted on these forums) moved to the new Australian site due to its Australian memberbase.
That was OK for some time, but then issues came up between E-Series members and AFF mods/admin. E-Series was being hosted by AFF, and both sides had differing views on how the club should be run. I won't go into details but I'll say that I was less than impressed with the way AFF handled it. I now have limited access on AFF due to my views on the issue (I used to be a donating member and a highly active poster on there, not anymore).
As a result, E-Series left AFF and set up their own forums. AFF created a rival E-Series club ("EANL") to fill the gap left by E-Series, and to poach newer members. Most of the senior/active E-Series members left AFF to stick with the E-Series club (and an offshoot "Boosted E-Series Club" was established, kind of like an E-Series elite/sealed section).
You'll be more than welcome at either site (E-Series or EANL/AFF), just be careful of what you say on AFF though, any mention of Boosted E-Series (or the E-Series Owners Club for that matter) will either get you banned or have your posts deleted/threads locked. E-Series Owners Club is a lot easier on new members though, it'd take a bit of an effort to get banned there, but if you ask something *really* dumb expect to cop a bit of a ribbing. It's (mostly) good-natured though so don't take it to heart if this happens to you.
If you join the EANL club (admittedly they're geared more towards newer/novice members), keep in mind that most of their tech files are from the original E-Series Owners Club.
Alternatively, if you're based in WA, there's an independent group with their own forum, called "Perth E-Series" (www.pertheseries.com)
. Firstly, because they're in the middle of whoop-whoop. Secondly, they're all mad-crazy about E-Series and are pretty friendly. Helps if you're from WA though (since it's a forum specifically for Western Australians)
