I did have a go at doing your sig Lord Excelsior, but I just hit a problem, the fact I don't have your desired font installed on my machine (which is a nice looking font). I tried to find something suitable, and the best I could come up with was what you see in the pics below.
I'll have a looksie sometime tomorrow, see if I have what you want (can't make any gurantees the font is available), but in the mean time, this post can at least bump the topic if anyone else would care to try.
Here's what I've done.
If the glow isn't strong enough, I can fix that. But if you just ain't happy with it, then that's cool - first time I've managed to do something like this with some success, albeit limited.
Let me know what you think (the first one looks a little dodgy, I tried to add another effect to give some depth.. with not much sucess).
