Sharing posts on DevTo and Twitter. Adding comments, encouragement, support where I can. This doesn't feel like a lot, so I will also try and find inspiration for more ways I can help!
I will also share the "Call to All Devs" at work and see if anyone else will get involved or has any ideas.
Figure out how to get more Women candidates (and employ more Women) Testers and Developers! If anyone has any details on how to make job-ads less off-putting to Women please let me know, because we really struggle to attract female candidates to apply.
Don't be afraid if it's a small step - start somewhere!
