However, there are some other places where you can try to get your theme listed. Some will simply link back to your website, and others will offer visitors direct downloads from their own websites. In general, make sure that you’re familiar and comfortable with the directory or gallery before submitting your theme. Some have been known to distribute themes with sponsored or hidden links.
