Since our chat function has been shut down for about 6 months, we're trying something new with Discord, a free chat service. 

If you're interested, please check out https://discord.gg/E7AKYQM

APC relies on donations to stay running. We got close to the target for 2017 (97%), and the goal has been reset for 2018.

However, we're falling behind already, with two months of the year gone, and less than a month's cost donated.

Please consider donation to help keep APC free for everyone. Thank you!!
