I have put up a new post over at TFCC, presenting some of the many new transgender caption blogs popping up these days.
By the way, if you want to make your own TG blog it is, in fact, very simple.
Google's Blogger allows for caption blogs of the explicit kind, as long as you tick of the "Adult Content" setting and let them set up a content warning.
Blogger is free, there seems to be no storage limit, it requires no HTML or programming skills, and there are a few decent templates to choose from. You may change the color scheme to suit your own needs and add new elements of your own choice.
The fact is that you do not even need to know how to use graphics software. You may upload a picture and add the caption as plain text in the blog post.
Make sure you set the settings "Let search engines find your blog?" and "Add your blog to our listings?" to Yes.
Let me know when you have published a few caps, and I'll add your blog to my list of transgender caption blogs.
Rachel has a guide on how to write your own caps.
