Old/Abandoned Addon Takeover?

[scootter]

I looked around but did not see any obvious answers. I apologize if I missed it.

Is there a procedure or proper way to take over and old addon in order to continue development on it? I of course want to include the original author in the details and credits but how should I handle this? Just keep the same name but upload it as a new version and new author?

Thanks for any information you can provide!
