I recently became a volunteer for a website called CaptVids. It is a website that provides closed captioning (subtitles) for a variety of YouTube videos for deaf or hard-of-hearing viewers (or foreign language speakers). If you're deaf or know anybody who's deaf, you should tell them about this site. They'd really enjoy it.
You can request certain YT videos to be captioned on their forum. There, you can also volunteer to become a captioner for their requested vids. They only have about 3 volunteers (including me) at the moment, and they could really use some help. The guy who runs the site is very nice, and you'll really get along with him.
So, if you're a good typer and like contributing to accessibility, this is the site for you. You'd might even want to put it on your resume. You can see some of my captioned vids here. Until next time, adios!
