I haven't learned the horrible new way Blender works, I have 2.62 but I never use it.
I gotta be honest. With all due respect, you're being a bit stubborn about versions. Yes, there's a big UI change, but it's a part of life, and from my personal experience, it's much easier to use with the new user interface once you learn it. You just have to give it time. At least a few days of practice. After all, you didn't just jump into Blender 2.4x right off the bat, did you? As well, the majority of hotkeys are unchanged. A minority have been changed to be more logical, but the vast majority (all the ones that I can remember) are unchanged. If you're like most 2.4x users, you mostly use hotkeys anyway, right? The biggest change is that the spacebar now opens a menu to search ALL functions (if I recall correctly, the 2.4x Blender used the spacebar to add objects). So if you know what a feature is called but don't know where it is on the menus or the hotkey, no fuss, just hit space and type the name. Say you want to extrude (hotkey "e") but can't remember the hotkey and don't know where it is in the menus (heck, I don't know offhand, though could probably find it easily enough), just hit space and type "extrude".
That's really it. Sure, some things are moved around and can be a pain to search for, but once you've found it, you now know where it is. The search function helps tremendously. Tons of new features were added in the 2.5x and 2.6x line (that's right, you're not one, but two generations behind). And 2.62 isn't the latest version either, it's 2.65.
And then there's addons. Sure, Blender 2.4x has addons, but they're all outdated now. If you want any new addons, they're not going to work with 2.4x unless they predate the 2.5x series and retained downloads for older versions (like the G3D support addon). In fact, let's look at the G3D support addon. The older versions actually have some bugs in them. They work, but not the way they're supposed to. You can't set the no-select flag (recently implemented into MegaGlest), you can't toggle between alpha and team colour independent of single or double sided objects. But beyond that, let's look at making things a bit more productive. Take the Dynamic Spacebar Menu addon, for example (which comes bundled with the 2.6x series, but is disabled by default; you can enable it in the user preferences). Without it enabled, spacebar brings up this menu:
Enable it and we got a more comprehensive menu to help you find stuff.
Of course, it's not a replacement for 2.4x's UI, but it's an alternative that makes it even easier to find the commands you're looking for. If you're emotionally attached to Blender 2.4x's colour scheme, you can get that back from changing the colour scheme in the user preferences:
Sure, even then, the UI is slightly different, but I'm of the opinion that Blender would be very much useable for a 2.4x user. The only critical change is getting used to using the search feature.
You're by no means required to upgrade on others behalves, but this is a community project, and the compatibility of models across generations of Blender remains to be seen.
