Geekcampsg call for volunteers
View cfv.txt
We are looking for volunteers to join us in organising GeekcampSG 2017[1]. It is essentially a community conference for geeks covering both software and hardware.
We are looking for each volunteer to take up a tiny portfolio, and hopefully more than 1 volunteer per portfolio for redundancy. First timers welcomed and mentorship will be provided if needed. Please let me know if you are interested to help, or be a speaker!
Off the top of our heads, these are the areas where help is needed:
- accounting + finance
- afterparty
- design
- Emcee
