I haven't had a chance to try out the plugin, but it looks promising ;-)
I am looking for a solution for external links.
Basically I want to have clean, user-friendly, permanent slugs on my own website, I can point to, which then get forwarded to cryptic external links...
I want to have one place to manage the ugly external urls, without being in need to update my whole website; also avoiding 404s from search engines indexing my site.
In a way similar to a customizable url shortener... or just a slug for the already built-in WP Links feature.
Did I just find my own answer while composing an email to you?
