Good news, the Stellar Community Forum has made it to the next round of voting in the Stellar Community Fund (SCF). If you have an account on Reddit and have posted to r/Stellar before, you'll more than likely be able to vote on Reddit here. I'd suggest reading the entire Reddit thread, but basically what you need to do in order to vote is:
Make sure you read all the rules and in the poll confirm this by selecting the option that you've read the rules
Leave a comment on the thread about who you want to vote for (you don't just vote for 1 project this time, you vote for a total of 4 - 3 main projects and 1 projects that deserves an honourable mention).
As Zac mentioned in the thread, the comment needs to be in this format (HM stands for honourable mention I think!):
HM. Project Name
If you enjoy the forum, we'd really appreciate a vote by having one of the 3 project names as Stellar Community Forum. Here's a link to the Reddit thread where you can vote.
