I've been building a browser based hex mapper and I'm starting to collect a few names for alpha testing. If you're willing to try a very early stage product, see how it works, and provide feedback to help improve it - please sign up below. All questions are optional (apart from your email address).
Note that this is an alpha product, so it can be expected to break, and you can't assume that all data will be faithfully saved. Definitely a 'use at your own risk' product.
