There are things that need to be freely donated. Like mod development and community leadership/administration, for the reasons mentioned.

The way to get an extension you need, if you cannot program yourself, is to ask for help in the "help wanted" section.

Believe you me I am a professional programmer and I build programs in c# .net every day, big complicated secure programs that run in a major enterprise. But the c++ stuff going on in FLHook development and assembler (exe hacking) is a totally different league. These guys are masters.

Also, anything you can think of you need, is probably already made. There is much they know, that cannot be found in these forums. Just ask.... Be friendly... use teamspeak / msn / skype / email.

There are things that require money and that aren't illegal. When your mod is released and you set up a community, it needs hosting. A dedicated hired Windows server (or co-located) in a server park that has connection to a main internet hub. The forums need hosting too. All that requires a constant stream of money and the backing/ownership of somebody with a solid real-life job (in addition to the paypal button that nobody uses)

C# and C++ are similar the more complicated is to understand how flhook and plugin are developped, and understand the logic of implementation, if you understand that, you WIN
At the momment, i dont understand all the things, but i try again
