Subject Re: [PROPOSAL] ECharts - proposal for Apache Incubation
Date Fri, 05 Jan 2018 18:51:18 GMT
Hi -

(1) This looks really cool and I would like to volunteer to Mentor the project.

(2) You mention that there are over 50 contributors, but only list 5 core developers. Are
the 5 core developers all from Baidu? Do you plan to quickly invite some of the other contributors?

Regards,
Dave

> ==== Homogenous Developers ====

at Baidu.
