I've been rather busy making packs to make it easier for editing your own maps, and to go with it I wrote a hex editing tutorial.
I hope it's much easier to understand. I also plan on making a few more tutorials to do with editing maps for online use very soon.

I hope now a few more people can have a go at making their own maps and having fun with it.
Any problems, leave a message here

Great tut, if I have some time left I iwll try it for sure

Thanks
If you're interested, I'll be writing a simple guide for adding tiberium clouds, lights, custom models etc in LevelEdit. As well as making it playable online

You gave me a nice Idea (something else to HeyEdit) no Maps, just the Renegade.exe
