I can likely work within your budget. I've been wanting a project to beef up my front-end skills.
Plus, I need to feed my cats. 🐱 🐈 :octocat:
Hit me up on the skypes, yariplus as well, or email works too, if interested. 😉
Quora allows people to edit title of their topics separately in the place that the title appears.
Sounds like something that should be part of a theme to me.
If you wanted to make such a theme, in-place editing isn't really difficult, you're just swapping visibility between a text block and a text input. Client-side you would only do the swap for the correct user(s), and then server-side verify and actually change the topic title.
