Hiya! I'm Mahaugher and I guess I should write something here...
I used to use Inkscape to make my vectors, but now I'm shifting towards Ponyscape which is a derivative of Inkscape. If you are an Inkscape user and want to check it out, go here:
[link] . It has a lot of really nice features including power-strokes and a lot of other fun things to make vectoring just a tiny bit easier.
I used to vector resources for anyone to use and as I was learning how to pony I moved on to sketches. However, these days I'm trying to push out completely original vectors with a unique style I have been working with.
Last few things I wanted to say here is that almost everything I make is free to use non-commercially. You are free to use it anywhere you want, all that I ask is for a little bit of credit and more importantly I would love to see how you use it. To the people who help share my work across tumblr, personal blogs and what have you I can't thank you enough! Every time I see it pop up somewhere I'm very, very thankful!
